OUTDOOR HEATER INSTALLATION
HEATER CLEARANCES – OUTDOOR
• In an outdoor installation it is important to ensure water is diverted from overhanging eaves with a
proper gutter/drainage system. CAUTION! If the heater is installed directly under a roof overhang, install
a 90° street elbow onto the vent terminal. Install a 2 ft (61 cm) pipe section onto the elbow. Install the
vent cap onto the end of the pipe. Direct the vent cap away from the house or building,
(see page 24).
• The heater must be set on a level foundation for proper drainage.
• This unit shall not be operated outdoors at temperatures below 32
If the heater is located under a roof or deck overhang, there must be at least three (3) feet (1 m) of clearance between
the bottom of the overhang and the top of the heater exhaust vent, see Figure 20. If the heater is under a roof or deck
overhang, the space around the heater must be open on three sides. DO NOT install the heater under any deck.
For minimum exhaust vent clearances for building openings, see Figure 25 on page 33.
In Canada, the heater must be installed with the top of the vent at least 10 ft (3 m) below, or to either side of, any opening
into a building.
Orient the heater for convenient access to the water connections and the gas and electrical connections.
Note: Check local building codes for installing the heater from any property line set back requirements (see Figure
17 on page 24 for installation illustration).
If installing the heater next to or near an air conditioning unit, heat pump or another gas pool heater, allow a
minimum of 36 in. (91.4 cm) between the unit and the heater.
