Leveling; Clearances For Service Access; Residential Garage Installation - Westinghouse WGR050NG076 Installation Instructions Manual


Location that could cause the system and heater to freeze and leak.

Incorrectly-sized expansion tank
6. Clean and flush system when reinstalling a heater.
NOTE: When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to
make note of the heater model and serial number.
B. LEVELING
In order for the condensate to properly flow out of the collection system, the area where you locate the heater must be level. Location
must also fully support the weight of the filled water heater.
C. CLEARANCES FOR SERVICE ACCESS
All water heaters eventually leak. It is recommended to install a catch pan beneath the water heater. This catch pan should be sized
with a maximum depth of 2", and a minimum diameter 2" greater than the diameter of the water heater. The catch pan should empty
into an open drain line. This drain line should be ¾" ID minimum, piped to an open drain. Failure to follow these instructions could result
in property damage. Such damages ARE NOT covered by product warranty.
Figure 1 – Recommended Service Clearances
NOTE: In addition, it is recommended to provide a minimum service clearance of 6" from the top of the water heater to allow for piping
of the T&P relief valve and top ports. Depending on the installation, this clearance may need to be substantially greater than 6".
NOTE: If you do not provide the minimum clearances shown in Figure 1, it might not be possible to service the heater without removing
it from the space.
The space must be provided with combustion/ventilation air openings correctly sized for all other appliances located in the same space
as the heater. The heater cover must be securely fastened to prevent the heater from drawing air form the heater room. This is
particularly important if the heater is in a room with other appliances. Failure to comply with the above warnings could result in
substantial property damage, severe personal injury, or death.
D. RESIDENTIAL GARAGE INSTALLATION
PRECAUTIONS
If the heater is located in a residential garage, per ANSI Z223.1:

Mount the bottom of the heater a minimum of 18" above the floor of the garage, to ensure the burner and ignition devices are
well off the floor.
