Oil Pump Details
The oil pumps depicted in this section represent the most
commonly used models, For models not depicted, such as the
Suntec Model J or H, refer to the pump manufacturer’s bulletin that
is supplied with the burner.

Combustion Air Requirements
Fresh air required to support combustion, as well as to provide
adequate location ventilation, must be supplied. All types of fuel
require approximately 10 cubic feet of standard air (sea level at 60
F.) per 1000 BTUs firing rate, for theoretical perfect combustion.
In actual practice, a certain amount of excess air is required to
ensure complete combustion, but this can vary substantially with
specific job conditions. Additional air is lost from the boiler room
through barometric dampers, draft
diverters and similar venting devices. It is generally accepted that
1/2 square inch of free air opening (for each gas or oil burner in the
room) per 1000 BTU/hr. firing rate will be adequate. Under no
circumstances should a boiler room be under negative pressure.
Jurisdictional authority relating to combustion air and boiler room
ventilation requirements vary widely. In order to make certain of
compliance, the controlling authorities should be consulted.
Burner Mounting - General
A properly installed and adjusted burner is the lowest cost
maintenance insurance you can buy.
Provisions should be made to provide adequate space around the
burner and associated equipment to allow for ease of inspection,
maintenance and service.
Observe codes for the minimum clearances to combustible
materials.
Provide a suitable burner front plate, consisting of a steel plate of
ample thickness to support the weight of the burner and hold it
firmly in alignment with the heat
