•
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 CPVC or Polypropylene (PPs) vent component systems approved under
ULC-S636 Standard for Type BH Gas Venting Systems , or stainless steel Type
BH venting systems* are to be used. Permitted PPs materials comprise Single
Wall Rigid pipe and fittings. Ensure compliance with exhaust temperature
limitations for the respective materials, which typically are:
•
ULC-S636 CPVC: 90°C (194°F)
•
ULC-S636 PPs:- 110°C (230°F)
For long vent runs with higher initial exhaust temperature, some jurisdictions may
allow the use of mixed materials for economy: CPVC for the initial run followed by
ULC-S636 approved PVC to the termination (It is the responsibility of the Installer
to confirm that local codes will allow this option). Ensure appropriate transition
glue is used. The installer is responsible to ensure that sufficient temperature
loss is allowed for in the CPVC section to fall below the 65°C (149°F ) upper limit
for PVC, taking into account the highest possible ambient temperature in the area
of vent travel (e.g. boiler room, attic and/or chase).
EXHAUST VENT MATERIAL – USA
IBC recommends that only CPVC or PPs vent component systems approved
under UL1738 (Standard for Venting Sustens for Gas Burning Appliances,
Categories II, III and IV), ULC-S636 Standard for Type BH Gas Venting Systems,
or stainless steel Type BH venting systems* are to be used but many local
jurisdictions in the USA still allow the use of PVC (Sch. 40 ASTM D1785 or
D2665 and fittings) or CPVC (Sch. 40/ASTM F441 with Sch. 80 fittings); or CSA
approved 3" stainless vent systems.
WARNING
Covering non-metallic vent
pipe and fittings with thermal
insulation shall be prohibited.
