BURNER PUMP
The burner is equipped with a single stage pump. When the pump is connected to a single feeder pipe, a
maximum rise of 8 feet is allowed. This height is measured from the tank outlet level to the burner inlet.
When the rise is more than 8 feet and not exceeding 10 feet, a by-pass plug (provided with the burner)
must be inserted in the pump and an oil return pipe must be installed.
For more details, see
“INSTALLATION INFORMATIONS”, Part No. 21844 on the burner pump.
If the rise is higher than 10 feet, a two stage pump may be required along with an oil return pipe.
3. APPLIANCE INSTALLATION
LOCATING THE UNIT
The furnace must be installed in a location where combustion air is available in sufficient quantity. In
airtight houses, the installation of an outside air intake might be required. (See details in 3- APPLIANCE
INSTALLATION, COMBUSTION AIR).
The owner is responsible for ensuring a proper installation to allow a salubrious operation of the
appliance.
Position the furnace so that the connecting pipe is as short as possible and limit the use of 90
o
elbows to
a minimum.
Provide sufficient clearance to permit easy access for maintenance of the filters, motors, controls and
pipe connectors.
