•
Place in operation the appliance being inspected. Follow the lighting
instructions. Adjust thermostat so appliance will operate continuously.
•
After it has been determined that each appliance remaining connected to the
common venting system properly vents when tested as outlined above, return
doors, windows, exhaust fans, fireplace dampers and any other gas-burning
appliance to their previous conditions of use.
•
Any improper operation of the common venting system should be corrected
so the installation conforms with the National Fuel Gas Code, ANSI Z223.1 -
latest edition. In Canada, all installations must conform with the current CAN/
CGA - B149.1 Installation Code and/or local codes.
1.4.1 Applications
All HC Series boilers must be installed as a Direct Vent venting system. The
combustion air must be piped in from the outdoors and connected directly to
the boilers combustion air connection. See section 1.4.7 for air intake piping
requirements.
1.4.2 Exhaust Vent Material
EXHAUST VENT MATERIAL – CANADA
Only PVC, CPVC, Polypropylene (PPs) or stainless steel* vent component
systems approved under ULC-S636 Standard for Type BH Gas Venting Systems
are to be used. Ensure compliance with exhaust temperature limitations for
the respective materials. The vent temperature is limited with the use of a flue
temperature sensor and software to ensure the maximum temperature of the
PVC venting material is not exceeded.
