Figure 22 – Sidewall Venting
ƽ WARNING: Do not combine the flue from this
unit with the vent from any other appliance. Do not
combine flues from multiple appliances into a
common vent. The flue from this unit must be a
dedicated stack.
Connect the flue vent directly to the flue outlet opening on the top
of the pool heater. Make the connections from the pool heater vent
to the outside stack as direct as possible with no reduction in
diameter. Provide adequate clearance to combustibles for the vent
connector and firestop. Follow the vent manufacturer’s instructions
when installing sealed AL29-4C vents and accessories, such as
firestop spacers, vent connectors, thimbles, caps, etc.
Provide adequate clearance to combustibles for the vent connector
and firestop.
When planning the venting system, avoid possible contact with
plumbing or electrical wiring inside walls, ceilings, and floors. Locate
the pool heater as close as possible to the chimney or gas vent. When
a vent system is disconnected for any reason, the flue must be
reassembled and resealed according to the vent manufacturer’s
instructions.
The installed length of flue from the pool heater to the outside point
of termination must not exceed 50 equivalent feet (15.2m). Subtract
5 feet (1.5m) of equivalent length for each 90° elbow. Subtract
2.5 feet (0.7m) of equivalent length for each 45° elbow.
Masonry Chimney Installation
Do not use a standard masonry chimney to directly vent the
combustion products from this pool heater.
To use a masonry chimney, the chimney must use a sealed,
corrosion-resistant liner system. Sealed, corrosion-resistant liner
systems (singlewall, doublewall, flexible, or rigid) must be rated for
use with a high efficiency, positive pressure vent system.
Corrosion-resistant chimney liner systems are typically made from
a high grade stainless steel such as AL29-4C. The liner must be
properly sized and fully sealed throughout the entire length. Both
the top and bottom of the masonry chimney must be capped and
sealed to provide a dead air space around the liner.
ƽ WARNING: Do not vent this pool heater into a
masonry chimney without a sealed stainless steel
liner system. Any breaks, leaks, or damage to the
masonry flue/tile will allow the positive-pressure flue
products to leak from the chimney and into
occupied living spaces. This could cause serious
injury or death due to carbon monoxide poisoning
and other harmful flue products.
IMPORTANT: Check with local code officials to
determine code requirements or the advisability
of using a masonry chimney with a sealed
corrosion-resistant liner system.
