this water heater.
2. Always install water heater exhaust vent / intake pipe terminations 12 inches
above maximum expected snow accumulation levels.

power supply could result in electric shock or fire.
Locate the water heater in a site where leakage from the water heater or
connections will not result in damage to the site adjacent to the water heater.
When such l
ocations cannot be avoided, it is recommended that a suitable drain
pan, adequately drained, be installed under the water heater. Install the
water heater in a location that allows for proper clearances to combustible and
noncombustible construction. Consult the rating plate for proper clearances.
Please refer to the installation manual before mounting the water heater.
Ensure the mounting location can support the weight of the filled water
heater.

front cover.
The gas connection fitting on the water heater is ¾” female NPT.
The supply line must be sized for the maximum output of the water heater model
being installed. If there are additional gas appliances connected to the same supply
line, size the supply line according to the COMBINED
total maximum BTUH draw for the appliances as if they were operating at the
same time.
DO NOT operate the water heater until all connections have been completed
and the heat exchanger is filled with water.
Ensure pipe material is suitable to meet local codes and standards. The pipe
