AWARNING
This water heater must not be installeddirectly on carpeting. Carpeting must be protected by a metal or wood panel beneaththe applianceextendingbeyond the full width and depth of the applianceby at least 3 inches(76.2mm) in an) direction,or if the applianceisinstalledin an alcoveor closet the entire floor must be coveredby the panel. Failureto hee¢ this warningmay result in a fire hazard.
Combustion Air and Ventilation
When determining the installation location for a power vent water heater, snow accumulation and drifting should be consid- ered in areas where applicable.
VENTING CLEARANCES
•0" clearance for 3" (and optional 2") PVC, ABS or CPVC Schedule 40 vent piping from combustible surfaces.
•12" minimum from the ground, 9" ceiling overhangs. Figure 2.
•The Power Vent outlet terminal shall terminate at least 36" above any forced air inlet located within 10 feet. Figure 3a.
&WARNING
Minimum clearances between the water heater and com- bustible construction are 0" at the sides and rear, 5" at the front, and 0" from the vent pipe. Clearance from the top of the jacket is 12". Provide 24 inches front clearance for servic- ing and adequate clearance between the jacket top & ceiling for servicing the flue area. (See Figure I). Refer to the label on the water heater adjacent to the gas control valve for all clearances.

_, WARNING
A gas water heater cannot operate properly without the cor- rect amount of air for combustion. Do not install in a con-
fined area such a closet, unless you provide air as shown in the "Facts to Consider About the Location" section. Never
obstruct the flow of ventilation air. If you have any doubts or questions at all, call your gas company. Failure to provide the proper amount of combustion air can result in a fire or explo-
sion and can cause DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
_,WARNING
If this water heater will be used in beauty shops, barber shops, cleaning establishments, or
with dry cleaning equipment, it is imperative that the water heater or water heaters be installed so that combus-
tion and ventilation air be taken from outside these areas. Refer to the "Facts to Consider About the Location" sec- tion of this manual and also the current edition of the National Fuel Gas Code, ANSI Z223.1, also referred to as NFPA 54 for specifics provided concerning air required.
•The Power Vent outlet terminal shall terminate at least 4 feet
below, 4 feet horizontally from or 1 foot above any door, win- dow or gravity air inlet into the building. Figure 3a.
•18" minimum in all directions from any obstruction that may interf?re. Figure 3b.
•18" minimum from other natural draft (gravity) direct vent,
power vent or power direct vent appliance inlet and/or outlet vent(s) when directly above or 135° to either side of center line.
Figure 3c
a24" minimum from any appliance inlet and/or outlet vents when directly below or 45 ° to either side of center line. Figure 3c.
•The location selection must provide clearances for servicing and proper operation of the water heater. Figure 4.
•Vent termination must not be within 4 feet of any items such as gas meters, gas valves or other gas regulating equipment.
•The venting system must be installed in a manner which allows inspection of the installation of the venting pipes and joints as well as periodic inspection after installation as required by ANSI Standards.
