INSTALLATION
Location - Select a location accessible to water lines, gas
supply (type identified on the rating plate), an adequate open
drain, and as close as practical to a chimney or gas vent. When
installed, the water heater must be level. To prevent excessive
heat loss through water piping, locate the water heater as close
as practical to the areas of greatest hot water usage. Do not
locate the water heater where lines could be subjected to
freezing temperatures.
Adequate clearances shall be provided for easy access to
controls by service personnel to enable proper cleaning,
servicing and operation of the water heater. Under no
circumstances is the front of the water heater to be placed in a
position where the burner tray assembly cannot slide out for
removal when servicing.
Clearance/Flooring - If the water heater is installed
directly on carpeting, it must be installed on a metal or wood
panel which extends beyond the full width and depth of the
water heater by at least 3 inches in any direction. If the water
heater is installed in an alcove, the entire floor must be
covered by the panel. A minimum of 24 inches front clearance
shall be provided for inspection and servicing.
This water heater may be installed in an alcove on combustible
flooring with clearances from combustible materials as shown
in Figures 1 and 2.
CAUTION
The National Fuel Gas Code (ANSI Z223.1 /NFPA 54)
expressly prohibits the following:
a) Installation of a water heater in a bathroom, bedroom, or
any occupied room normally kept closed.
b) Installation of a water heater in a garage, unless the unit
is installed so that the burner and ignition devices are at
least eighteen (18) inches above floor level and protected
to avoid damage by moving vehicle. See Figure 3.
