Heater Installation Procedure - FireLake 155 Owner's Manual

HEATER INSTALLATION PROCEDURE

1) Select a location for your heater observing minimum clearance to combustibles. Consider
that maintenance and cleaning will be required. Allow adequate work space around burner
and stack. Mount heater as low as code allows, easing service and keeping your heat at
floor level. Select a noncombustible area or observe minimum clearances to combustibles.
For best operation minimize distance of horizontal chimney runs. Do not exceed 8' in

length. Horizontal runs must have a minimum 1/4" rise per foot. Clean horizontal runs
every 500 hours of use or as needed. Ash will accumulate here and block draft.
draft causes poor flame, backpressure, oily buildup, unreliable ignition. Use a draft inducer
if draft is marginal or inconsistent.
3) If suspending the heater use (4) 3/8, 1/2, or 5/8 diameter all-thread and tie into the provided
brackets at each end of the cabinet. The mount brackets are designed to attach at the top or
bottom of the heater ends to meet various field mounting needs.

4) WASTE OIL FURNACES ARE DEPENDENT ON PROPER DRAFT FOR EFFICIENT
BURNING. ASSURE THAT ADEQUATE MAKE-UP AIR IS AVAILABLE. NEGATIVE

5) If permanent masonry chimney is not available, use appropriate diameter multi-wall
manufactured chimney and collars listed for use with oil fired furnaces per UL 103 or All
Fuel Class A. Locate for easy connection to the furnace and install per manufacturers'
instructions and local building and fire codes.

6) The chimney must extend a minimum 3' above the highest roof line within 10'. In general
you will need a minimum of 2 feet of vertical for each foot of horizontal for best draft.
7) Use a stack that is equal diameter to the furnace outlet. Use minimum 24 gauge single wall
connector pipe between furnace outlet and damper.
chimney and have a path into fire chamber. This will create a rusting environment. Install
a chimney tee near the furnace to act as a cleanout / water trap.
8) Locate barometric damper near the furnace and face away from blower. Its opening must be
visible from the floor and out of strong air flows that could falsely affect its ability to
regulate. Read instruction sheet included with damper.
Never let the weight of the heater rest on the weaker center
