All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Do not store or use gasoline or other
ammable vapors and liquids or
corrosive materials in the vicinity of
this or any other appliances. Cements
for plastic pipe should be kept away
from all sources of ignition. Proper
ventilation should be maintained to
reduce the hazard and to minimize
breathing of cement vapors.
Never use open ame or smoke from
a cigarette, cigar, or pipe as a testing

Venting

Adhere to the following venting requirements:
1. The boiler can be installed with either sealed combustion or a conventional
venting arrangement. With either venting con guration, the di erence
in pressure readings at the boiler exhaust connection and air intake
connection cannot exceed 1.0" W.C. This equates to 70 feet (21.3 m) and 8
elbows when combining the distances on the air intake and exhaust with
the piping diameters matching the standard connections.
2. The pressure at the boiler exhaust connection must not exceed 0.05" W.C.
negative. This pressure must remain relatively constant throughout the
operation of the boiler.
3. The boiler should not be operated with a negative pressure in the boiler
room (unless there is sealed combustion [intake piped outside]). Pay
particular attention to other equipment installed in the boiler room such as
compressors and air handling units.
4. Consult your venting pipe supplier for assistance with sizing of vent
materials and other potentially required accessories.
NOTE: An air intake lter is included as standard. The air intake lter must be
inspected and, if required, cleaned and/or replaced on a monthly basis at a
minimum.
