Matrix Installation and Operation Instructions
3.0 VENTING
The NY Thermal Matrix is a high efficiency condensing gas furnace/boiler utilizing induced power venting. Exhaust gases are to
be vented directly outdoors, using the venting method detailed in this section. Under no conditions, may this unit vent gases into a
masonry chimney, unless it is vacant, and utilizes Matrix approved venting material as illustrated in the figures in this section.
Attaching Vent Piping to Boiler
It is extremely important for the intake and exhaust piping to be adapted to the appropriate size immediately upon exiting the boiler
cabinet. The Matrix comes with a 3” male PVC fitting to connect the air intake port of the boiler.
The Matrix exhaust connection is 3” male PVC, use approved cement to connect to venting system.
Check the fl ue outlet gasket for proper insertion a nd sealing prior to and after attac hi ng the ve nting.
Ensure the venting system does not apply a load or stain on the flue outlet of the boiler (recommend using two elbows to create a
“swing joint” as shown above).
IMPORTANT
The vent connection and piping must be perfectly aligned to the furnace connection. AND MUST NOT
APPLY ANY WEIGHT OR LATERAL FORCE TO THE FLUE BOX. NTI does not warranty damages to the flue
box.
It is recommended that two elbows be
used, so that the slo
e of the horizontal
exhaust vent does not affect the vertical
lumb of the
i
e connected to the boiler.
Slo
e all horizontal indoor exhaust
venting ¼” to ½” per linear foot.
Figure 3.1 Venting Construction
It is recommended to have a collection
oint
for condensation in the intake ventin
.
Condensation can then be drained to an
open house drain or condensate pump.
Drain line from intake must have an
a
ro
riate tra
or shut off valve to avoid
siphoning.
