Proper location for installing your heater

Carefully select the location of the water heater. For your safety
and for proper heater operation, you must provide combustion
air to the heater and properly vent the exhaust gases.
Follow the guidelines below:
▶ 1. Locate the heater where venting, gas and plumbing
connections are feasible and convenient.
▶ 2. The hot water lines should be kept short and insulated to
save energy. It is recommended to locate the water heater
as close as practical to the most frequently used hot water
fixtures.
NOTICE:
Risk of appliance freezing!
▶ The water in this water heater is cold and always remains
cold except for the times the burner is on. In the event of
power outage in conjunction with freezing temperatures,
the heater should be drained.
See chapter 7.2, page 57 "Winterizing" for draining
instructions.
