STA-RITE SR333LP - Manual (Page 15)

The terminal must be located (Canada):
• at least 10 feet (3.3M) from any opening into a building.
• at least 12” (.3M) above finished grade or the normally
expected snow accumulation level, whichever is higher
• At least 4 feet (1.2M) horizontally from electric meters,
gas meters, regulators and relief equipment
• At least 7 feet (2.1M) above grade adjacent to walkways
or similar traffic areas.
Allow at least three feet (1M) vertical clearance over vent
termination when terminating under an overhang or deck.
Avoid corners or alcoves where snow or wind could have
an effect. Exhaust may affect shrubbery and some building
materials. Keep shrubbery away from termination. To pre-
vent staining or deterioration, sealing or shielding exposed
surfaces may be required.
8. Fire Hazard. Do not run the heater vent
into a common vent with any other appliance. Do not
run the Special Gas Vent into, through, or within any
active vent such as a factory built or masonry chimney.
Final Installation Check:
Check that horizontal vent pipe runs slope uniformly at
least 1/4” per foot (2cm per meter) to condensate drain(s).
No sags, no dips, no high or low spots.
Check that vent is supported at elbows, tees, and horizon-
tal and vertical runs according to manufacturer’s instruc-
tions and code requirements.
Check that vent supports and wall and ceiling penetrations
allow free movements up, down, and sideways without
putting any strains on the heater or vent body.
Check for at least six inch (15cm) free air clearance
between the heater vent pipe and combustible materials.
Check that all joints are completely together and sealed.
WATER CONNECTIONS
The heater requires proper water flow and pressure for its
operation. See Figures 15 and 16 for the recommended
installation. The filter pump discharges to the filter, the fil-
ter discharges to the heater, and the heater discharges
directly to the pool or spa.

* Minimum vent length is one foot (.34M), or in accordance with
vent manufacturer’s instructions, and local and national codes.
Horizontal vents 3’ (1M) or less in length do not require a conden-
sate tee, but must slope down toward the outlet at 1/4” to the foot
(2cm/M) to allow condensate to drain.
