RE: SNOW-MELTING SYSTEM
BOWMANVILLE FIRE STATION
Dear Lou-Ann,
The following is a quotation for the replacement of the /
present electric snow-melting system with a hot water
system. I have been inst�dl.ing the hot water system for the
past nine years and it has proven itself to be very
reliable and -trouble fret system. �
Instead of electric cables being buried in concrete, 3/4"
high density polyethylene pipes are run on 9" centres up
and down the ramp. They are fed with a 2" supply line to
the top and the water is collected at the bottom in a 2"
return line . The ,/ pipe, Dupont "Sclairpipe" , is quite
flexi,ole, accommodaf,'ting ground movement easily as well as
expansion and coptraction of the concrete . Being polye-
thylene plastic ' t does not corrode as would metal. pipes
and is nearly identical to the gas piping that is used to
oring service to/ one ' s home .
It is also rated at series #160 which is 8 times the normal.
operating pressure and is not affected by most liquids i .e
salts and acids .
(cont ' d.
f�
3 , (a)
. . ./2
Each joint is heat welded together at 2500 C. so once the
system is installed the joints will not come apart.
In order to heat the water I met with Mr. Tony Galloway of
Superior Plumbing & Heating. The present boiler does not
have enough additional capacity to heat the ramp and the
building both. Consequently, we are recommending an
additional gas boiler be installed in the boiler room to
supply only the ramp heating system. I have included prices
for both a standard unit and a high efficiency unit. Based
on figures supplied by Consumer Gas, the operating cost for
a standard boiler are 28% less than for an electric system,
and the high efficiency boiler is 46% less than an electric
,oiler. In addition, the hot water system includes 2
thermostats that will supply the heat only upon demand.
The following is a proposal of work to be done :
TLaff7bvA L.
A. �— ; of existing concrete slab only at bottom and at
top of slab (approximately 15 feet either end) to
maintain present entrance slope and street grade .
B. Installation of Dupont polyethylene piping as per
attached specifications) 6X6X#6 welded wire mesh over
piping to reduce concrete cracking.
C. Installation of boiler and connection to gas supply,
ramp supply and ramp return lines . Install thermostatic
controls .
D. Test system at 40psi for leak detection.
E. Pour 5-6" concrete slab over piping. Concrete will be
30 MPA, class A exposure rating, designed for truck
traffic .
F. Fill with 50 : 50 mixture of glycol-water and start up
system.
Price .
a) Ra;np replacement, concrete and
piping only $10, 500.00
b) Installation of Standard
Boiler & Thermostat 4, 500.00
c) Installation of High Efficiency
Boiler 8, 000.00
(cont ' d. . ./3 )

Guarantee:
We will provide a guarantee on the ramp for a period of 5
years provided it is operated in accordance to specification.
I recognize that my quotation is higher than your present
quote for replacement of the electric system. However, I
feel that because of the greater reliability, efficiency,
and the reduced operating costs of the hot water system it
should be very seriously considered.
Even though I have an oovious personal interest in seeing a
not water system installed, I frankly feel it is a much
better system. If you wish references as to its merits or
to my a.pilities as an installer I will be harpy to provide
them.
Having said all the above, I did contact an installer of
electric ramps, Sandy Smith of Mountsberg Electric . Sandy
and I have shared clients who have both systems and my
sources indicate that he is a reputable tradesman. We met
on the ramp last Thursday night and I am passing along his
comments to you. Sandy told me that it appears that the
electric service to*111ramp is not sufficient . Based upon
Pyrotechnic ' s requirement, the supplier of the cable, the
ramp require' 44 , 000 watts/per hour minimum. Sandy could
only find a supply of 25, 000 watts . I suggest you check
with your present quote to see if this is a problem. If you
are persuaded to retain the electric heating system you may
negotiate with him directly. His phone number is
416/659-7309 .
In conclusion, thank you for your consideration. Should
there be any clarification, question or representation
required, please do not hesitate to contact me .

GENERAL SPECIFICATION FOR THE
INSTALLATION OF SNOW MELT SYSTEMS
USING HIGlI DENSITY POLYETHYLENE PIPE
1 . 0 Scope
1 . 1 This specification is intended as a criteria for
glycol circulating snow melt piping systems for
used on garage ramps, patio slabs and bridge decks .
1 . 2 This specification covers basic design, material
selection and installation requirements for snow
melt systems using high density polyethylene pipe
and fittings .
I
2 .0 Design Consideration
2 . 1 Piping systems used for snow melt application are
exposed to cold and hot temperature variations ,
induced stress, corrosive elements and traffic
loading and it is for this reason that special
consideration be given to using materials and
techniques capable of withstanding such conditions .
2 . 2 Selection of materials, joining techniques and
controls outlined in this specification will
provide ultimate long term results .
NOTE : Materials or techniques of lesser value should not
be contemplated.
3 . 0 Material Selection
3 . 1 Polyethylene compounds used to manufacture pipe
and fittings shall be classified as defined in
ASTM Standard D1248 Specifications for Polyethylene
Moulding and Extrusion Materials .
Polyethylene pipe standards shall be in accordance
to CGSB - Canadian Government Specifications Board
Standard 41-GP-25-1977 .
3 . 2 Polyethylene pipe for headers and returns Shall be
PE 3507 , Series 160 ( 1 00 psig rating 0 23 degrees
C . ) high density resin as manufactured by Dupont
of Canada in straight lengths or approved equal. .
/2
3 . 3 Polyethylene pipe for runs shall be 3/4" 1 . P . S.
Series 160 High density as manufactured by Dupont
of Canada or approved equal. .
3 . 4 Polyethylene fittings shall be socket fusion types
rated at 125 psi pressure service of compatible
material . Saddles shall be heat fused type rated
at 125 psi as manufactured by Dupont of Canada or
approved equal .
3 . 5 Fill fittings shall be made of steel socket fused
transition to saddle fittings as manufactured by
Dupont of Canada or approved equal .
3 . 6 Flanged connections shall be used to tie into
exposed steel piping to heating units .
I
4 . 0 Preparation and concrete Breakout for Existing Systems
4. 1 Existing steel pipe systems intended for replace-
ment shall have the concrete surface slab removed
where needed using concrete breaking equipment .
Remove corroded steel pipe . Clean and patch base
slab .
4 . 2 Partial. breakout of concrete surface slab at either
or both ends may be all that is required on
existing ramps that are long enough and gentle
enough in slope . Such procedure should be brought
to the owners attention for approval .
5. 0 Fabricating Polyethylene Piping Network
5. 1 General : Joining .polyethyl.ene pipe is precise but
rapid and gives joints that are as strong as the
pipe itself . An electrically heated joining tool
melts a thin layer on the inside of the coupling
and the outside of the end of the pipe . The molten
surfaces are joined and left to cool resulting in
a strong integral joint . Heating times are guide-
lines for ideal conditions . Field personnel_ may
have to extend heating times due to weather
conditions . In case of high winds , the tool should
be shielded in an insulated container to prevent;
excessive heat lost .
/.3
5 . 2 Socket fusion procedure to 2 " , 3" and 4" polyethy-
lene pipe and fittings.
- Chamfer pipe ends to aid in centering.
- Use depth gauge and cold ring to ensure proper
socket penetration and alignment .
- Check to see that heating tool temperature is
about 265 degrees C . ( 500 degrees F. )
- Time or count out heating cycle '( 25 seconds
duration) once fitting and pipe are in place on
tool .
- Snap tool straight out of fitting and off pipe .
- Line up pipe and fitting carefully when ,joining
parts together and hold in place for 25 seconds .
5. 3 Saddle fusion procedure for 2 " , 3" and 4" polyethy-
lene pipe and fittings.
- Support the pipe to maintain straightness during
the fusion.
- Place saddle fitting on tool and pre-heat for
about 15 seconds then place tool and saddle
squarely on main applying about 60 to 80 lbs .
of force for a period of 50 seconds .
- Snap off saddle from tool. and place squarely to
melt pattern on main and hold for about 25
seconds .
- Drill_ out hole through saddle outlet before
proceeding.
5. 4 Make tip collector and return headers using proper
pipe size and fuse saddles on the main at 9" on
centres for the required width of the area to be
heated .
5 . 5 Socket fuse pre-measured lengths of cont-inous 3/4"
Polyethylene pipe between headers ( 10 sec . heat ) .
5 . 6 Tie in collector and return 11c!aders Co supply
piping using flanges .
J . (
/4
5 . 7 Install one fill fitting at the highest point on
the system and install a drain valve at the lowest
point .
6 . 0 Pressure 'Testing for Leaks
6 . 1 Blank off or shut supply piping to polyethylene
system and connect test fittings and gauges .
6 . 2 Using a nitrogen bottle and regulator apply 40 psi
pressure to the polyethylene system . Remove
nitrogen bottle and leave piping under required
pressure for 1 hour . Soap test all saddle fittings
and connections for leaks .
I
7 . 0 Concrete Surface Slab
7 . 1 Concrete :
( 1 ) Concrete shall be ready-mixed conforming to
CSA A23 . 1-1973 .
( 11 ) Maximum concrete slump shall be 4" and shall
be specified pump mix where concrete pumper
is used.
( 111 ) Provide air entrained concrete for concrete
sections exposed to salts or freeze-thwa
action. Air content to be minimum 4/,
maximum 7%.
( 1V) Concrete surface to be wood trowel finished .
7 . 2 To minimize random cracking due to the natural
shrinkage of concrete as it cures, slabs larger
than 15 feet should have control joints - grooves
l.inch deep and 1/8 inch wide - cut in the partially
set concrete with a grooving tool . Inexperience
with a masonary saw may result in piping and/or
reinforcing being damaged. This method of grooving
should not be used.
8 . 0 Filling, Bleeding and Placing into Operation
8 . 1 Remove caps from fill pipe . Make sure the drain
valve is closed and that the supply valves to the
heating unit are opened .
V
/S
8 . 2 SlOWly fill the system with 50-50 etylene glycol-
water mixture allowing air to escape .
8 . 3 When full , start up circulating pumps to force out
any air that may have been trapped in the system.
Continue to release air from the highest point in
the system until it is removed . In some cases this
may take one or two hours .
8 . 4 Turn on heater and allow to heat up to normal
operation temperature . Check pressure during
heating up time to make sure it does not exceed 30
psi . Bleed off if necessary .
9 . 0 Normal Operating Pressure and Temperature
9 . 1 Normal operating pressure is between 10-15 psig at
normal operating temperature .
9 . 2 Normal operating temperature is 120 degrees F. and
the supply line shall be thermostatically
controlled not to exceed this limit .

Attention: Mr . J.A. Aldridge
Dear Sir :
The following is a price quotation to replace the electric snow
melting cables in the underground entrance ramp at fire hall at 132
Church Street.
KREMCO proposes the following:
1) To prepare the ramp surface prior to laying the first coat
of mastic asphalt. (proposed size 29 X 44 feet)
2) To provide a 1 inch deep key at the top and bottom of the
ramp to minimize grade changes and help anchor the mastic asphalt.
3) To lay a base coat (approx 3/8" thick) of mastic asphalt.
4) To install three new Pyrotenax heating cables to cover an
area of 1188 square feet, at a power loading of 22.8 watts per square
foot with an average cable spacing of 7 . 5 inches. This cable layout
would leave an unheated width of 1 foot 0 inches on each side of the
ramp. This power loading will match the existing system that is now
installed.
5) To cover the heating cables with a layer of expanded steel
mesh reinforced mastic (approx 1/2" thick) , then apply a road wearing
surface (approx 3/4" thick) .
6) To connect the cables to the existing power supply and
controls .
7 ) To clean up the work site and remove all debris.
8 ) To supply all labour and materials .
9) To warrant the operation of the heating cables for a period
of three years from the date of installation. Should the cable(s)
fail during this period Kremco shall repair or replace the cable(s)
at our option.
