installation and servicing
for models
Figure 8 shows the clearances required for installation and
servicing.

required.
5.2 - Clearances from
combustible material
This boiler may be installed directly onto a wall of
combustible material with the following clearance:
Ceiling: 2 inches (51 mm)
Front: 2 inches (51 mm)
Rear: 0 inches (0 mm)
Sides: 2 inches (51 mm)
Floor: 2 inches (51 mm)
Concentric vent: 0 inches (0 mm)
Split vent (first 12” from the boiler): 1 inch (25 mm)
Split vent (after 12” from the boiler): 0 inches (0 mm)
5.3 - Choosing the
installation location for
45WN and 45AN models
CAUTION!!! The boiler must be installed on a
vertical wall constructed to bear its weight or the
boiler and building may be damaged.
NOTE: The boiler must never be installed on
carpeting.
CAUTION!!! This boiler is not designed for
direct outdoor installation. If installed outside of the
structure that it supplies hot water too, it must be
sheltered so it is protected from rain, wind, sun and
frost. NEVER place this boiler in a location that would
subject it to temperatures at or near freezing. Failure
to properly locate this boiler can result in premature
failure voiding the warranty.
When locating the boiler the following factors must be
considered:
• the location of vent/air intake terminals;
• connection to the gas supply;
• connection to the water supply;
• connection to the heating system;
• connection to the domestic hot water system;
• connection to the electrical supply;
• disposal of the condensation produced by the boiler;
• connection to the room thermostat;
• piping of the safety relief valve discharge;
• possible connection of the outdoor temperature sensor;
• possible connection of an indirect storage tank, see
section 7.
