Installation and Service Manual
Vertical Combustion Air Inlet Clearances
You must locate the air inlet termination elbow at least 12" (30cm) above the roof or above normal snow levels.
If the air inlet cap is within a 10 foot (3.05m) radius of the flue outlet, the point of termination for the combustion air inlet cap must be at least 3 feet (0.91m) below the point of flue gas termination (vent cap).
Do not install the combustion air inlet cap closer than 10 feet (3.05m) from an inside corner of an
Horizontal Combustion Air Inlet Clearances
You must locate the horizontal air inlet termination point at least 12" (30cm) above grade and above normal snow levels.
If the air inlet cap is within a 10 foot (3.05m) radius of the flue outlet, the point of termination for the combustion air inlet cap must be at least 3 feet (0.91m) horizontally and 12 inches (30cm) below the point of flue gas termination (vent cap). Do not install the horizontal combustion air inlet cap above the flue outlet.
Do not install the combustion air inlet cap closer than 10 feet (3.05m) from an inside corner of an
Multiple Sidewall Direct Vent Installations
The combustion air inlet caps for multiple pool heater installations must maintain the same minimum clearance from the closest flue vent cap as specified in single pool heater installations. You may install multiple flue outlet caps
Maintain all clearances and installation requirements for multiple pool heater installations.
6. Outdoor Installation Venting
IMPORTANT: Before installing a venting system, follow all venting clearances and requirements found in the Venting, General Information section, page 10.
These pool heaters are
WARNING: Only install outdoor models outdoors and only use the vent cap supplied by the pool heater manufacturer. Personal injury or product damage may result if any other cap is used or if an outdoor model is used indoors. Properly install all covers, doors and jacket panels to ensure proper operation and to prevent a hazardous condition.
Combustion air supply must be free of contaminants (see Combustion and Ventilation Air, page 7). To prevent recirculation of the flue products into the combustion air inlet, follow all instructions in this section.
Outdoor Vent/Air Inlet Location
Keep venting areas free of obstructions. Keep area clean and free of combustible and flammable materials. Maintain a minimum clearance of 3" (76mm) to combustible surfaces and a minimum of 3" (76mm) clearance to the air inlet. To avoid a blocked air inlet or blocked flue condition, keep the outdoor cap air inlet, flue outlet and drain slot clear of snow, ice, leaves, debris, etc.
Do not install outdoor models directly on the ground. You must install the outdoor pool heater on a concrete, brick, block, or other
Do not locate the pool heater so that high winds can deflect off of adjacent walls, buildings or shrubbery causing recirculation. Recirculation of flue products may cause operational problems, bad combustion or damage to controls. Locate unit at least 3 feet (0.91m) from any wall or vertical surface to prevent wind conditions from affecting performance.
Multiple pool heater outdoor installations require 48" (1.22m) clearance between each vent cap. Locate the outdoor cap at least 48" (1.22m) below and 48" (1.22m) horizontally from any window, door, walkway or gravity air intake.
Locate the pool heater at least 10 feet (3.05m) away from any forced air inlet.
Locate pool heater at least 3 feet (0.91m) outside any overhang.
Clearances around outdoor installations can change with time. Do not allow the growth of trees, shrubs or other plants to obstruct the proper operation of the outdoor vent system.
Do not install in locations where rain from building runoff drains will spill onto the pool heater.
