Boiler Location - NTI Matrix Installation And Operation Instructions Manual

3.0 BOILER LOCATION

In all cases, the Matrix must be installed indoors in a dry location where the ambient temperature must be
maintained above freezing and below 100F [38C]. Gas 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.
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 150 ft
is not required). Each ventilation air opening must meet the minimum requirements of 1 in
. The lower ventilation opening must be located within 6" of the floor while the upper

not less than 100 in
opening must be located 6" from the top of the space.
Closet Installations
For closet installations, it is necessary to provide two ventilation air openings, each providing a minimum area
2
equal to 1 in per 1000 Btu/hr, but not less than 100 in
See Table 3-1 for minimum recommended 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" [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 recommended clearances.
Residential Garage Installations
When installed in a residential garage, mount the boiler a minimum of 18" [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.

Notes:
1 6" if surface is removable allowing 24" clearance (i.e. closet installation).
2 Clearance can be as low as 12" on one side, if clearance on the other side is 24".
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.
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 150 ft
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 4-2 for a
list of approved materials.
Closet/alcove installations in US and Canada require approved CPVC, Polypropylene or
Stainless Steel vent and air-inlet pipe, fittings, cements and primers (Table 4-2).
