Step 6 — Oil Burner
This furnace is supplied with a high- -pressure atomizing retention
head- -type burner (for use with grade 1 or 2 Fuel Oil). The
mounting flange is fixed to burner air tube and no adjustment is
required for insertion length. The oil pump is set to operate on a
single line system. To operate on a two- -line system the by- -pass
plug must be installed.
Step 7 — Oil Connections
Complete instructions for installing fuel oil piping can be found in
oil burner Installation Instructions included with furnace.
Oil line entry holes are provided in side panels. Two holes are
provided in each location so that a 2- -pipe system may be used if
desired.
An oil filter should be installed as close to burner as possible with
ALL oil burners and is essential on lower firing rate burners. We
recommend the use of a low- -pressure- -drop oil filter such as the
General Filter, Inc. model #1A- -25A or equivalent.
Step 8 — Barometric Draft Control
The barometric draft control shipped with furnace MUST be used
with furnace to ensure proper operation. Instructions for installing
control are packed with control.
Step 9 — Blocked Vent Shut- - Off (BVSO) For Chimney
Venting
All oil furnaces installed in Canada must have a Blocked Vent
Shut- -Off.
Refer to Fig. 8- -13 and the installation instructions supplied with
the Blocked Vent Shut- -Off for installation and wiring procedures.
The Blocked Vent Shut- -Off must be installed in the flue between 2
in and 12 in from the furnace outlet and between the furnace outlet
and draft regulator. (See Fig. 9.)
