Installation must be in accordance with local codes, or,
in the absence of local codes, with the latest editions
of the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
and the National Electrical Code, ANSI/NFPA 70. In
Canada installations must conform with the current
CAN/CSA B149 and the Canadian Electrical Code
Part 1 CSA C22.2 No.1. Where required by the author-

Installation base
The heater should be mounted on a level, non-com-
bustible surface. Heater must not be installed on
carpeting. The heater can be installed on a com-
bustible surface only when the appropriate listed floor
shield base is provided. An optional listed floor shield
base is available for factory installation with the heater
on all indoor models. Do NOT use the shipping base
crate as an installation base.

In addition, the heater shall be installed such that the
gas ignition system components are protected from
water (dripping, spraying, rain, etc.) during appliance
operation and service (circulator replacement, control
replacement, etc.).

NOTE: The heater should be located in an area
where water leakage will not result in damage to the
area adjacent to the appliance or to the structure.
When such locations cannot be avoided, it is
recommended that a suitable drain pan, adequately
drained, be installed under the appliance. The pan
must not restrict air flow.
