Installation Codes; Clearances; Outdoor Heater Installation - Rheem Raypak 207A Installation And Operation Manual

IMPORTANT NOTICE: These instructions are intended
only for the use by qualified personnel, specifically
trained and experienced in the installation of this type
of heating equipment and related system components.
Installation and service personnel may be required by
some states to be licensed. If your state is such, be sure
your contractor bears the appropriate license. Persons
not qualified shall not attempt to fix the equipment nor
attempt repairs according to these instructions.
NOTE: The heater should not be located in an area
where possible water leakage will result in damage to
the area adjacent to the heater or to the structure. When
such locations cannot be avoided, it is recommended
that a suitable drain pan, with adequate drainage, be
installed under the heater. The pan must not restrict
combustion air flow.
RECOMMENDATION: For regions with snow, Raypak
recommends installing these units indoors.

Installation Codes

Installation must be in accordance with local codes, or,
in the absence of local codes, with the latest edition of
the National Fuel Gas Code, ANSI Z223.1/NFPA54 and
National Electrical Code, ANSI/NFPA 70, and for Canada,
the latest edition of CAN/CSA-B149 Installation Codes,
and Canadian Electrical Code, CSA C22.1 Part 1 and
Part 2.

Clearances

All Heaters
For indoor and outdoor clearances from combustible
surfaces, see Table B.
When installed according to the listed minimum clearances
from combustible construction, the pool heater can still be
serviced without removing permanent construction around
the heater.
However for ease of servicing, we recommend a clearance
of at least 24" (610 mm) in the front, and at least 18"
(457 mm) on the water connection side. This will enable
the heater to be serviced in its installed location, that is,
without movement or removal of the heater.
Clearances less than these may require removal of the
heater to service either the heat exchanger or the burner
tray. In either case, the heater must be installed in a
manner that will enable the heater to be serviced without
removing any structure around the heater.
Flooring
This heater can be installed on combustible flooring.
The combustible clearances listed can be reduced by
protecting the exposed combustible surfaces as shown in
Table C.

Outdoor Heater Installation

These heaters are design-certified for outdoor installation,
when equipped with the approved tops designated for
outdoor use.
WARNING: The heater shall not be located in an
A
area where water sprinklers, or other devices, may cause
water to spray through the cabinet louvers and into the
heater. This could cause internal rusting or damage
electrical components. Such damage is not covered
under warranty.
WARNING: Do not install within 3' (0.9 m) of a heat
A
pump or an outdoor condensing unit. Strong air intake
from this type of equipment can disturb the combustion
process and cause damage or personal injury.
