Installation & Operation Manual │ FTG
3.0 BOILER LOCATION
In all cases, the FTG boiler must be installed indoors in a dry location where the ambient temperature must be
maintained above freezing and below 100F [38C]. All boiler components must be protected from dripping,
spraying water, or rain during operation and servicing. Consider the proximity of system piping, gas and
electrical supply, condensate disposal drain, and proximity to vent termination when determining the best boiler
location.
Water or flood damaged components must be replaced immediately with new factory-
approved components as failure to do so may result in fire, serious injury, or death.
Floor Mounting
The FTG boiler can be mounted directly on combustible flooring, with the exception of carpeting. Installing the
boiler on carpeting is not permissible. Ensure the boiler is mounted above any anticipated flood level. Units
include factory supplied/field installed leveling legs. Once the unit is removed from the pallet, thread the
leveling legs into the allocated threaded inserts in the bottom of the unit.
Boiler Area Ventilation Air Openings
If boiler area clearances are less than the recommended clearances specified in Table 3-1, the boiler area must be
ventilated. EXCEPTION: if the boiler area/room has a volume of 365 ft
3
or greater (275 ft
3
for models FTG
600-800; 320 ft
3
for models FTG 1200-1400), ventilation of the boiler room is not required. Each ventilation air
opening must meet the minimum requirements of 1 in
2
per 1000 Btu/hr., but not less than 100 in
2
. The lower
ventilation opening must be located within 6 in. of the floor while the upper opening must be located 6 in. from
the top of the space.
If the "Boiler Area" does not meet the recommended clearances listed in Table 3-1, and if
the boiler area has a volume less than 365 ft
3
, it is considered a Closet or Alcove. In
US/Canada, PVC vent pipe and fittings shall not be used within the closet or alcove; only
approved CPVC, Polypropylene or Stainless Steel vent pipe and fittings can be used. See
Table 4-4 for a list of approved materials. Under all circumstances, the minimum
clearances listed in Table 3-1 must be provided.
Closet Installations
For closet installations it is necessary to provide two ventilation air openings as shown in Figure 3-1, each
providing a minimum area equal to 1 in
2
per 1000 Btu/hr., but not less than 100 in
2
and within 6 in. of the top
and bottom of the closet door. See Table 3-1 for minimum clearances.
Alcove Installations
Alcove installations have the same minimum clearances as closet installations, except the front must be
completely open to the room at a distance no greater than 18 in. [457 mm] from the front of the boiler and the
room is at least three (3) times the size of the alcove. Provided these conditions are met, the boiler requires no
extra ventilation air openings to the space. See Table 3-1 for minimum clearances.
Residential Garage Installations
When installed in a residential garage, mount the boiler a minimum of 18 in. [457 mm] above the floor. Locate
or protect the boiler so it cannot be damaged by a moving vehicle. Check with your local authorities for other
possible regulations pertaining to the installation of a boiler in a garage.
Table 3-1 Minimum Clearances for Installation and Service
Notes:
1
6 in. if surface is removable allowing a minimum of 24 in. clearance (i.e. closet installation). See Ventilation Air
Opening dimensions in Figure 3-1.
2
Recommend allowing 24” clearance on at least one side for servicing, clearance on opposite side can be as little as 4”.
3
Notice: the rear of the boiler must be accessible for installation and service.
