requirements section of this manual.
7. Before removing any guards or performing any maintenance, be sure
that the main power supply is disconnected.
COMBUSTION AIR ADJUSTMENTS:
NOTE: Proper combustion air adjustment must be achieved using a
certified combustion analyzer and smoke tester to ensure complete
combustion.
The air adjustment should be made to achieve 10% CO
2
and No. 1 or “trace”
smoke. (Bacharach Scale)
SETTING THE AIR
ADJUSTMENT PLATE
A) Regulation of the combustion air
flow is made by adjustment of the
manual AIR ADJUSTMENT PLATE (1)
after loosening the FIXING SCREWS
(2 & 3). The initial setting of the air
adjustment plate should be made
according to Column 5 in the Burner
Set-up Chart.
B) The proper number on the manual
AIR ADJUSTMENT PLATE (1) should
line up with the SETTING INDICATOR

- 11 -
(4) on the fan housing cover. Once set, the air adjustment plate should be
secured in place by tightening SCREWS 2 and 3.
C) The final position of the air adjustment plate will vary on each installation.
Use instruments to establish the proper settings for maximum CO
2
and a
smoke reading of zero.
NOTE: Variations in flue gas, smoke, CO
2
and temperature readings may be
experienced when the burner cover is put in place. Therefore, the burner
cover must be in place when making the final combustion instrument readings,
to ensure proper test results.

TEMPERATURE FEELER GAUGE ADJUSTMENT
(ATTACHED TO FAN SWITCH)
The temperature feeler gauge is required to be always touching the heater
exchanger.
The temperature feeler gauge controls the air flow over the fan switch, which
eliminates any unnecessary fan cycling. The temperature feeler gauge can be
adjusted for different outside temperatures, by rotating the location of the
temperature feeler gauge holes. This will provide maximum performance of the
unit in different applications.
If supply air is warm (-5º C, indoor application):
Turn the temperature feeler gauge so that the holes are parallel with the heat
exchanger. This will help the fan switch to remain cool and not overheat. See
following:
If supply air is cold (under -5ºC):
Turn the temperature feeler gauge so that the holes are closed off as the air goes
over the heat exchanger. This will reduce fan cycling and the unit from shutting
down. See following:
In extreme cold conditions, cover the holes on the temperature feeler gauge
using foil tape or replace feller gauge with part# FV-433B Solid feeler gauge.
Ensure that the temperature feeler gauge is readjusted for warmer weather
conditions. Failure to do so may result in burning out fan switches- not covered
under warranty.

5 and the last line 0.
OIL LINE CONNECTIONS
Note: Pump pressure must be set at time of burner start-up. A pressure gauge is
attached to the PRESSURE PORT (8) for pressure readings. Two PIPE
CONNECTORS (5) are supplied with the burner for connection to either a single or a
two-pipe system. Also supplied are two ADAPTORS (3), two female 1/4” NPT, to adapt
oil lines to burner pipe connectors. All pump port threads are British Parallel Thread
design. Direct connection of NPT threads to the pump will damage the pump body.
Riello manometers and vacuum gauges do not require any adaptors, and can be safely
connected to the pump ports. An NPT (metric) adapter must be used when connecting
other gauge models.
