Safe operation at the proper gas manifold pres-
sure requires correct sizing of supply gas pipe. The
Gas Installation Code AG601 also offers general
criteria for gas piping (see Section 2D).
If the above installation requirements are not
followed, the fuel used in these appliances could
produce and expose you to substances that are known
to cause cancer or reproductive harm.
Install the heater in accordance with all local
codes and ordinances and the most recent edition of the
Gas Installation Code AG601.
Do not operate this heater outdoors at tempera-
ture below -7°C.
WARNING
The heater must be tested to ensure
operation is satisfactory before the installer
leaves.
2B. Outdoor Installation
2B-1. Heater Clearance
Locate the heater in an open, unroofed area, (see
Fig. 2) and maintain the following clearances:
Blank side and
150 mm Minimum
rear of heater
Piping side
300 mm Minimum
Front of heater
450 mm Minimum
Floor
Noncombustible*
*If you are installing the heater on a combustible
surface, use an approved noncombustible base.
Do not install the heater in a location where
leaves or other combustible materials can gather
around the base or on the top.
Do not locate the heater close to sprinklers; the
water could damage the controls and the electronics.
If you are installing the heater under an overhang,
there must be a minimum clearance of 1.5 meters
above the top of the heater. The area under the over-
hang must be open on three sides. Protect the heater
from direct water drainage.
WARNING
Minimum clearances between the heater and
any opening into the building must be
maintained.
IMPORTANT:
High wind conditions may
cause downdrafting problems in the heater. To mini-
mize downdrafting problems in high wind areas, locate
the heater at least 900 mm from vertical surfaces, such
as nearby buildings and walls.
Special Precautions for Propane Gas Heaters
Propane gas is heavier than air, so do not
install pool heater using propane gas in pits or other
locations where gas might collect. Locate the heater a
safe distance from propane gas storage and filling
equipment. Consult local codes and fire protection
authorities about specific installation restrictions.

Notes:
1. Blocks must provide solid base and be braced so they
cannot slip out of place.
2. Air openings in blocks must be arranged to provide
unrestricted opening through entire width or length of
base.
