HYBRID HMF150 AS A "ADD ON" TO EXISTING FURNACE

THE INSTALLATION OF THE FURNACE MUST BE DONE IN ACCORDANCE WITH RULES OF
AUTHORITIES HAVING JURISDICTION AND THE CAN / CSA B365-01 (R2006) STANDARD FOR SOLID
REQUIRED COMPONENTS:
CAUTION
1. Certifi ed for series connection to the supply plenum outlet only (upstream) of an oil-fi red furnace or gas
fi red furnace, or electric furnace;
2. May be added onto one of the following:
• an oil furnace having an oil input, as shown on the original nameplate, maximum fi ring rate 91,000
BTU/h
• a gas fi red furnace having a gas input, as shown on the original nameplate, between 60,000 minimum
and 80,000 maximum BTU/h
• an electric furnace having a rating as shown on the original nameplate, between 15 minimum and 20
maximum KW
3. Do not connect duct work so that a reverse fl ow is possible;
4. Operate the original furnace (oil, gas, electric) unit periodically to ensure that it will operate satisfactorily
when needed;
5. Do not relocate, bypass or render inoperable any of the safety controls in the original furnace installation;
6. Maintain suffi cient combustion-air supply to both furnaces. Air starvation is dangerous, see Section 3.2
"Outside Combustion Air";
7. Refer to manufacturer's instruction.
8. Do not use duct elbows having an inside radius of less than 150 mm (6 in).
9. An add-on unit shall only be installed on a furnace duct system and chimney that are in good operating
condition.
10. a) The differential static pressure between the inside and outside of the warm air supply plenum, or the
air-temperature rise at equilibrium across the original furnace is to be measured before any changes are
made to the system. Using the following methods the differential of pressure and temperature should be
adjusted to the same values after the add-on installation (meeting original manufacturer specifi cations)
in order to maintain the air fl ow through the original furnace.
• on a belt-driven system, blower pulleys and motor pulleys may be changed but the electrical current
fl owing through the motor shall not exceed the nameplate rating (a blower motor of larger power
may be used);
• on a direct-drive system, the motor shall not be changed; however, the speed of the motor may be
increased;
