Venting Connections - PENSOTTI PCC 34-H Instruction Manual

3.10 Venting
Improper venting of boiler can result in excessive levels of carbon monoxide which can result in
severe personal injury or death. This boiler must be vented in accordance with the "Venting of
Equipment" section of the latest edition of the ANSI Z223.1 / NFPA 54 Natural Gas Code and/or the
"Venting systems and air supply for appliances" section of the latest version of the CAN/CSA B149.1
Natural Gas and Propane Installation Code in Canada and in accordance with all applicable local
building codes.
Venting Guidelines
For best results, keep the vent system as short and straight as possible.
Locate the boiler as close as possible to the vent termination.
The boiler vent must not be common vented with any other gas appliance or vent stack.
Slope vent upwards towards the vent terminal at a rate of 1/8" per foot (1% slope).
Vent termination must be a minimum of 12" above grade or expected snowfall.
Vent and air intake pipe must be supported every 4 feet of horizontal run and every 5 feet of vertical run.
PENSOTTI and Direct Vent
All PENSOTTI
which draw all of their required combustible air directly from outside the building.
All PENSOTTI b o i l e r s use a 3/ 5" c o nc e nt r ic v e nt or a 2 p ip es s ys t em t ha t u s es a 3" diameter
exhaust and a 3" diameter air intake pipe.
Use only vent and air intake systems certified with the boiler.
The air intake vent materials can be made of ABS, CPVC, PVC materials and in accordance with all
applicable local building codes.
Contaminated Make-Up Air Will Damage the Unit
We recommend not operating the boiler in an area that is or will be under construction or renovation.
The PENSOTTI warranty will not cover damage and premature wear caused to the unit due to installation
in a contaminated environment.
All exhaust venting connections must be leak checked with a soap solution upon initial start up of the
boiler. Any leaks must be repaired before continuing operation of the boiler.
All concentric venting must be checking for cross contamination using a combustion analyzer inserted into
the makeup air test port on the venting adapter. Analyzer must NOT read anything in excess of "0 ppm"
Carbon Monoxide (CO). Any leaks must be repaired before continuing operation of the boiler.
Warranty will not be available if the boiler is used for construction heat.
