Clearances To Combustibles
Minimum clearances between water heater and
combustibles are 0mm (0”) at the sides and rear, 140mm
(5.5”) from the front and 305mm (12”) from top (standard
clearance.) If clearances stated on the heater differ from
standard clearances, install water heater according to
clearances stated on the heater (see Figure 12).
Floors With Carpeting
This water heater must not be installed directly on
carpeting. Carpeting must be protected by a metal or wood
panel beneath the appliance extending beyond the full
width and depth of the appliance by at least 76mm (3”) in
every direction, or if the appliance is installed in an alcove
or closet, the entire
fl oor must be covered by the panel.
Failure to heed this warning may result in a fi re hazard.
Clearances For Servicing
When installing the heater, consideration must be given to
proper location. Location selected should be as close to
the wall as practicable and as centralized with the water
piping system as possible.
Servicing this appliance, such as changing the anodes,
etc. requires clearances for accesability and replacement
of parts. The anode could be as long as 0.89m (35”).
Refer to the current edition of the “Natural Gas and
Propane Installation Code” B149.1 for detailed
requirements.

Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual.
• Install water heater in accordance with the
instruction manual and B149.1.
• To avoid injury, combustion and ventilation air
must be taken from outdoors.
• Do not place chemical vapour emitting products
near water heater.
Breathing Hazard - Carbon Monoxide Gas
WARNING
HIGH AMBIENT TEMPERATURE INSTALLATIONS
As the room temperature rises, the water heater venting
is exposed to high temperatures from the inside and the
outside. In these situations, attention to the choice of
venting material is necessary. Establishing the ambient
temperatures where the heater and the venting are
installed is very important. Areas that can experience
high ambient environments include closets, alcoves,
areas under staircases, attics (especially in metal roofed
buildings), areas with restricted air movement, rooms with
large solar gains, metal sheds, industrial or commercial
enterprises and venting systems exposed to direct
sunlight. Water heater installations in ambient conditions
hotter than 43°C (110°F) require the installation of a high
ambient limit switch (kit number 9009024015) and use of
CPVC or polypropylene venting material.
Failure to install
the proper vent material will result in a non-compliant
installation and can result in deformation/breakage
of the pipe.
Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual.
• Flue gases may escape if
vent pipe is deformed,
broken, or not properly
connected.
Breathing Hazard - Carbon Monoxide Gas
WARNING
Important Notes and Warnings
•
This heater is certi fi ed to be installed using Schedule 40
PVC or CPVC or polypropylene plastic vent material. All
jurisdictions in Canada require that the material used to
exhaust combustion products is approved to ULC S636.
Only use approved material. All venting material and
components must be joined with the approved primer/
cleaner and solvent cement.
•
Do not common vent this heater with any other
appliance.
•
During operation the plastic piping will expand as it
heats up and contract as it cools down. This is normal
for this type of venting. Rigidly fastening the vent piping
can cause undue stress that may result in the cracking
or fracturing the vent piping material. A fracture of the
venting pipe may pose a serious safety hazard. To
prevent stressing of the vent system, all hangers and
supports must allow the vent piping freedom to move.
•
Use long sweep elbows wherever possible. Closely
coupled elbows and short radius elbows can reduce
the venting capacity.
•
All power vented water heaters generate a certain
amount of operational noise. In order to minimize
noise transmission to the support structure, it is
recommended to use isolation pads between the pipe
hangers and the vent pipe.
