2.3 INSTALLATION CODES
INSTALLATION MUST COMPLY WITH THE REQUIREMENTS OF AUTHORITIES HAVING
JURISDICTION. All local and national codes governing the installation of oil burning
equipment, wiring and venting must be followed. Some of the applicable codes are:
CAN/CSA B139 Installation Code for Oil Burning Equipment.
NFPA 31 Installation Code for Oil Burning Equipment.
ANSI/NFPA 90B Warm Air Heating and Air Conditioning Systems.
ANSI/NFPA 70 National Electrical Code.
CSA C22.1 Canadian Electrical Code.
ANSI/NFPA 211 Chimneys, Fireplaces, Vents and Solid Fuel Burning Appliances.
The latest versions of the above codes that have been approved for use in the location of the
installation must be used.
2.4 INSTALLATION
ELECTRICAL Wire according to the National Electrical Code (Canadian Electrical Code in
Canada) or local codes. Use a separately fused #12 electrical line directly
from the service panel to the furnace junction box. Install a manual shut off
switch at the door or stairway to furnace room so furnace can be shut off
remotely.
VENT PIPE See NFPA 31 (USA) or CSA B139 (Canada) code. Breech is certified for 3”
ULC S636 PVC vent pipe in Canada or PVC/CPVC schedule 40 pipe rated
for 140°F in the United States. Keep vent/flue pipe as short as possible.
BREECH The Paradigm is rear breech only.
RETURN AIR Ensure that the furnace return air temperature does not go below 50°F
(10°C).
2.5 VENTING
The Kerr Paradigm condensing furnace can be vented vertically through the roof or
horizontally through the wall. The low stack temperature allows the use of PVC vent. The
approved vent is vent meeting ULC S636 standard in Canada or PVC/CPVC schedule 40 pipe
rated for 140°F in the United States. IPEX System 636 in 3 inch diameter is recommended
for the Paradigm. The Installation Methods to be used are detailed in the manual available at:
http://www.ipexinc.com. An online Solvent Cementing Course is also available at that site.
The minimum vent linear length is 5 feet. The maximum equivalent length allowed after the
condensate trap is 80 feet. Each 90° elbow accounts for 8 feet. As an example if the system
has 5 elbows after the condensate trap, 40 lineal feet of vent can be used.
The vent is connected to the furnace using the supplied neoprene coupling. This coupling
attaches directly to the plastic collector. The furnace connection with the condensate trap is
shown in the figure below. The reducing tee and 1/2” connection are supplied. The supplied
tubing is connected to the condensate neutralizer.
