9 The warm-air supply outlet of the supplementary furnace should not be connected to the cold-air
return inlet of the central furnace because a possibility exists of components of the central furnace
overheating and causing the central furnace to operate other than intended.
9 DO NOT USE DUCT ELBOWS HAVING AN INSIDE RADIUS OF LESS THAN 6 INCHES
(150MM) ON THE (oil, electric, gas) furnaces.
9 DO NOT CONNECT DUCTWORK SO THAT A REVERSE FLOW IS POSSIBLE.
9 OPERATE THE (gas, oil, electric) FURNACE PERIODICALLY TO ENSURE THAT IT
WILL OPERATE SATISFACTORILY WHEN NEEDED.
9 THIS APPLIANCE IS CERTIFIED FOR INSTALLATION ONLY AS SHOWN IN THIS
INSTALLATION MANUAL. SEE DIAGRAMS ON PAGES 21-24
9 DO NOT RELOCATE OR BYPASS ANY OF THE SAFETY CONTROLS IN THE
ORIGINAL (gas, oil, electric) FURNACE INSTALLATION.
9 DO NOT CONNECT TO ANY GAS FURNACE THAT HAS NOT BEEN CERTIFIED
INITALLY AS COMPLYING WITH CAN/CGA-2.3
9 A GAS FITTER WHO IS RECOGNIZED BY THE REGULATORY AUTHORITY MUST
VERIFY THE OPERATION OF THE GAS FURNACE FOR ACCEPTABLE OPERATION
BEFORE AND AFTER INSTALLATION OF THE ADD-ON APPLIANCE.
9 DO NOT CONNECT TO ANY GAS FURNACE THAT IS NOT EQUIPPED WITH AN AIR-
CIRCULATION BLOWER, OR TO A CHIMNEY OR VENT SERVING A GAS FURNACE
OR GAS APPLIANCE.
9 THE MAGNUM 7500 CORN/WOOD PELLET FURNACE IS COMPATIBLE WITH THE
FOLLOWING (gas, oil, electric) INPUT SIZES: 50,000 to 200,000 BTU.
9 The Magnum 7500 Corn/Wood Pellet furnace should only be installed on a furnace duct system and
venting that is in good operating condition.
9 The installation of the Magnum 7500 Corn/Wood Pellet furnace should comply with requirements of
CAN/CSA-B365, and changes to the installation should comply with CSA B139 (for oil-fired), C22.1
(for electric), or CAN/CGA-B149.1 or CAN/CGA-B149.2 (for gas-fired)
Prior to installation you will need to determine the compatibility of the existing furnace to the
Magnum 7500 Corn Furnace. Following are the guidelines for determining compatibility.
CFM compatibility would be rated at app. 1250 CFM. If the cfm in the central furnace is less than this a
back draft damper may need to be installed in the plenum of the central furnace. The static pressure in the
ductwork cannot exceed the name plate rating on the central furnace and must be compatible with the
static pressure rating on the name plate of the Magnum 7500 Corn Furnace.
Adjust the static pressure in the ductwork to maintain a temperature rating of 130-150 deg. F.
