26. BURNER PUMP
When the tank is located below the unit, the basic single course pump, powered by a single duct, can
compensate for a drop of 8 feet (244 cm) measured between tank outlet and the height of entry into the
burner.
When the rise is more than 8 feet (244 cm) and not exceeding 10 feet (305 cm), 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 (305 cm), a two stage pump may be required along with an oil return pipe.
27. APPLIANCE INSTALLATION
A Blocked Vent Switch is mandatory for installation with an oil fired appliance that
normally operates with its vent system under a negative pressure. This device is
intended to detect a blocked vent system, responds to hot flue gases backing up
through its heat transfer tube, and can be wired to shut off the oil burner. It requires
manual resetting.
