Location Requirements
The water heater must be installed indoors in an area not
subject to freezing temperatures and in a vertical position
on a level surface. Water heaters located in unconditioned
spaces (e.g., basements etc.) may require insulation of the
water piping, drain piping and venting to protect against
condensation.
The water heater must be installed on a non-combustible
floor, as close to the chimney as practical. Select a location as
centralized within the piping system as possible. The heater
should be located in an area where leakage of the tank or
connections will not result in damage to the area adjacent
to the water heater or to lower floors of the structure (see
“IMPORTANT” notice on the following page). Before installing
this water heater, consideration and planning must be given
to the following details:
• Proximity to walls and other objects (see Figure 1 through
Figure 3).
• Access to oil supply (see "Oil Supply").
• Routing and support of the vent piping and termination
(see "Vent and Exhaust Connections").
• Position of water supply and placement of water piping
and floor drain (see "Water Supply").
• How and where to obtain combustion and ventilation air
supply. (see "Air Requirements").
• Connection to the electrical service. (see "Electrical
Supply").
