4. Locate the water heater on a level surface.
5. Locate the water heater near a oor drain. The water heater
should be located in an area where leakage of the tank or
connections will not result in damage to the area adjacent to
the water heater or to lower oors of the structure. When such
locations cannot be avoided, it is recommended that a metal
drain pan, piped to adequate drain, be installed under the water
heater. Drain pan should be fabricated with sides at least 45
mm (1-3/4”) deep with diameter at least 50 mm (2”) greater than
diameter of heater. Pan must not restrict combustion air ow.
6. Locate the water heater close to the point of major hot water
usage.
7. Locate the water heater close to a 120 Vac power supply. See
Electrical Supply
(page 33) for requirements.
8. Locate the water heater where an adequate supply of fresh air
for combustion and ventilation can be obtained. See
Combustion
Air and Ventilation
(page 13).
9. Locate the water heater where the vent and intake air piping,
when installed, will remain within the maximum equivalent
lengths allowed. See
Planning the Vent System
(page 14).
10. Do not locate the water heater where noise (such as
the Combustion Blower) during normal operation will be
objectionable in adjacent areas.
11. Do not locate the water heater where the subsequent installation
of the vent (exhaust) or intake air terminations would be
objectionable due to noise at the termination(s). This includes
locations close to or across from windows and doors. See
Power
Direct Venting (PDV)
(page 18) and
Power Vent (PV)
(page 25).
Read instruction manual before
installing, using or servicing
water heater.
• Do not store or use gasoline or other flammable vapours
and liquids in the vicinity of this or any other appliance.
• Avoid all ignition sources if you smell gas.
• Do not expose water heater control to excessive gas
pressure.
• Use only gas shown on rating plate.
• Maintain required clearances to combustibles.
• Keep ignition sources away from faucets after extended
period of non-use.
Fire or Explosion Hazard
WARNING
Do not ocate water heater areas where ammable liquids (vapours)
are likely to be present or stored (garages, storage and utility areas,
etc.): Flammable liquids (such as gasoline, solvents, propane (LP or
butane, etc.)) and other substances (such as adhesives, open paint
cans etc.) emit ammable vapours which can be ignited by a gas
water heater’s ignition device or main burner. The resulting ashback
and re can cause death or serious burns to anyone in the area.
Installation: Do not install the water heater where flammable
products will be stored or used.
Vapours from flammable
liquids may explode and
catch fire causing death or
severe burns.
Do not use or store flamma-
ble products such as gaso-
line, solvents or adhesives in
the same room or area near
the water heater.
Keep flammable products:
1. far away from heater,
2. in approved containers,
3. tightly closed and
4. out of children's reach.
Water heater has a main
burner and hot surface igniter.
The hot surface igniter:
1. can be triggered at any
time and
2. the hot surface will ignite
flammable vapours.
Vapours:
1. cannot be seen,
2. are heavier than air,
3. go a long way on the floor
and
4. can be carried from other
rooms to the electrodes
by air currents.
Flammable Vapours
FLAMMBLE
When the water heater is installed directly on carpeting, the water
heater shall be installed on a metal or wood panel extending beyond
the full width and depth of the water heater by at least 75 mm (3”) in
any direction or, if the water heater is installed in an alcove or closet,
the entire oor shall be covered by the panel. The panel must be
strong enough to carry the weight of the heater when full of water.
