OPERATING INSTRUCTIONS

TO START HEAT WITH GENISYS CONTROL

1. Ensure unit is on flat, level ground before starting, canopy and fan guards must be closed.

2. Flip switch to “OFF” position
3 Check fuel level ( 2-4 gallons to start)

4. Plug in supply cord to 115 volt outlet.

5. Flip switch to “MANUAL” position.

6. For thermostat operation flip switch to “THERM” position.

7. There will be a 5 second safe start check, a 45 second pre purge then the burner will fire.

IF HEATER FAILS TO START

1. Press manual reset button on burner relay.

2. Check for low voltage condition and 115 volt supply.

3. Check fuel filter, suction tubing and nozzle assembly

NOTE: If unit has been reset a number of times without ignition there will be an

accumulation of oil in the combustion chamber! Do the Following:

1. Make sure unit is sitting on level ground to ensure excess oil drain out of secondary
exchanger (via small drain hole located on outer shell of heat exchanger by burner end).

2. Allow unit to drain for 15-20 minutes or until all oil has drained out.

3. Upon ignition excessive amounts of smoke will be present until all excess

oil has been burnt from the heat exchanger.

4. When the unit has stabilized and the burner set up to operate properly, shut off

the switch. Let the fan cool down the chamber and stop.

IF UNIT STILL DOES NOT START REFER TO THE TROUBLE SHOOTING GUIDE PAGE 13

CAUTION

1. Do not start heater when excess oil has accumulated in chamber.

2. Do not fill tank while unit is operating.

3. Do not shut off by disconnecting supply cord. The heat exchanger

should be properly cooled before power shutdown.

4. In no case should extension cords be smaller than 12 A.W.G. and no

longer than 100 feet.

5. Do not use gasoline, crankcase oil or heavier than No. 2 furnace oil.

6. Always maintain adequate fuel supply.

ELECTRICAL REQUIREMENTS:

15 amp circuit IDH400QR
15 amp circuit IDH400QRC

TO STOP HEATER

Flip switch to “OFF” position. The burner motor will continue to run for 2 minutes to help cool the heat
exchanger and electrodes. The supply fan will continue to operate until the heat exchanger
has sufficiently cooled. Do not disconnect main power until supply fan has stopped running.

WARNING!: BEFORE MOVING ANY GUARDS OR SAFETIES DISCONNECT

THE MAIN POWER AS THE SUPPLY FAN WILL CYCLE
AUTOMATICALLY.

IDH MAINTENANCE INSTRUCTIONS

!WARNING!: Heaters should be fully serviced annually to ensure proper

performance. Maintenance should be performed by trained personnel

only. Incorrect maintenance may result in improper operation and

serious injury.

HIGH LIMIT SWITCH

It is recommended that the limit switch should be checked every heating season to ensure the switch
limits the temperature to 250oF (IDH400QR) 290°F (IDH400QRC) (This can be done by restricting the

air

flow through the unit. After tests are complete, remove all restrictions.

FAN SWITCH

The fan switch has been selected to allow for preheating of the heat exchanger to ensure that
only heated air is allowed to enter the space. Upon satisfying the need for heat, the fan switch will
continue to run the supply fan until the heat exchanger has cooled sufficiently. This feature will
help prolong the life of your heat exchanger.

FUEL FILTER

Replace cartridge (48164 or 48164A)once every week of normal usage or sooner, depending
upon fuel quality.

FLAME DETECTOR

To test the cad cell, start the burner and before the safety lock-out timing period ends,
disconnect the cad cell wires from the F-F terminals on the control. Next, jumper the F-F
terminals with a piece of wire. This will allow the burner to continue running so that you will be
able to check the cad cell resistance during the run cycle. If you did not get the F-F terminals
on the control jumpered before the burner locked out, wait 3-5 minutes before attempting this
again. With the burner running, connect the ohmmeter across the cad cell leads. Your signal
should be between 250-1200 ohms. If higher, please clean the cad cell eye or replace.

BURNER

The electrode spacing must be checked and adjusted, if necessary after every nozzle
change. Nozzle should be replaced annually or sooner if burner cannot be set up to
operate properly. Nozzle size and type are marked on the rating plate.

ELECTRICAL

Ensure all conduit (BX) connectors are tight. Check inside connections in control box to ensure
good connections. Check marrettes.

FAN

Check for dust or dirt build up on blades. Check for tightness of the set screw. Run heater to

check for fan vibration. Replace fan blade if vibration is noticeable.

MOTORS

No lubrication is necessary since the bearings are the sealed type. Clean motor of existing dust or dirt.

FUEL SYSTEM

Periodically remove fuel tank drain plug and clean tank. Do not store unit containing

furnace oil for long periods. The quality of fuel oil will affect light off at low ambient

temperatures, #1 fuel oil or kerosene are recommended for temperatures below

-10o C/8oF. (see page 8 for recommended settings if using #2 fuel oil in cold temperature)
FUEL PUMP

Check fuel pump pressure on a regular basis. This can be checked at the bleeder screw.

ADD 10 LBS TO THIS READING TO GET THE TRUE PRESSURE.

There is a pressure loss when fuel passes through solenoid valve. Example: IDH400 pressure

should be read at the port as 150 PSI, then the reading at nozzle line will then be 140.

HEAT EXCHANGER

If a smokey condition continues even after adjusting the air band assembly, the heat exchanger
should be thoroughly cleaned as per next page.

CLEANING PROCEDURE

1. Remove front cap. (48205 or 48205A)

2. Remove cover panel (jacket to front). (48119)

3. Remove fan thermostat cover on outer jacket (the one nearest the burner). (48112A)
Loosen thermostat and remove from the jacket. Remove high limit thermostat

cover.(48112). Remove the two screws that are on jacket, at the 3’o’clock & 9 o’clock
position 8 inches from front of unit.

4. Slide heat exchanger out of jacket and place front face down on floor.

5. Access for combustion chamber and heat exchanger cleaning is obtained through
the burner head opening and by removing the heat exchanger cap ring(s) (50115).

6. To reassemble, reverse procedure. If you need assistance, please contact the factory.

Close canopy and ensure fan guards are in proper position before trying to restart the unit..

COMBUSTION AIR ADJUSTMENTS

****For proper combustion air adjustment a calibrated gas analyzer and smoke tester should be
used to ensure complete combustion. Air adjustment should be made at the correct input and be
adjusted to achieve 10% CO2. For optimum combustion efficiency the combustion air control should be

set to provide no more than a No. 1 smoke (Bacharach Scale). The Beckett burner has a calibrated air
band, which will assist in adjusting the primary air for a good oil/air mixture. Adjust air band supply by
loosening lock screws and moving air shutter (B48254) and if necessary the bulk air band. Begin by
reducing the air until the unit begins to produce smoke. Increase air until no smoke is produced. Check for
excessive heat build up in the heat exchanger. Insufficient air will cause flame impingement and reduced
heat exchanger life. Increase air until heat build up has been eliminated. Check for proper ignition. Once
satisfied re- tighten all screws and locking mechanisms.

This adjustment is to be carried out while the unit is operating and after 5 minutes of firing. Rotating the air
bands on the burner housing makes the adjustment.

***Note: The above settings are approximations based upon clean equipment in proper working
order below 1000 ft. elevation. Combustion air adjustments will vary with location, altitude and
type of fuel used.

Colder ambient conditions may require less air and higher altitudes may require

more air. (ie. Set shutter on IDH400QR to 6 or 7 in very cold conditions to improve light-off. )

Due to the increased density of #2 oil at colder temperatures, kerosene fuel must
be used or the oil nozzle may need to be changed as follows at temperatures
below 8'F/-10'C.

TEMPERATURE FEELER ADJUSTMENT THAT IS ATTACHED TO THE FAN SWITCH

ALWAYS MAKE SURE THAT THE TEMPERATURE FEELER IS TOUCHING THE HEAT EXCHANGER!!

The temperature feeler provides air flow over the fan switch, which regulates the cycling of the fan.
The temperature feeler can be adjusted for different outside temperatures, by rotating the location
of the temperature feeler holes. This will provide optimum performance of the unit in different
applications, and will reduce or eliminate unnecessary fan cycling.

IF SURROUNDING AIR IS WARM (EG., -5 C or 23 F, indoor application):

TURN THE TEMPERATURE FEELER SO THAT THE HOLES ARE PARALLEL WITH THE HEAT
EXCHANGER, AND ENSURE THAT NOTHING IS BLOCKING THE AIR FLOW (EG., SCREWS).
BY DOING THIS THE FAN SWITCH WILL REMAIN COOL AND NOT OVERHEAT. (SEE FOLLOWING)
The fan switch is located under the high limit/fan cover which is mounted on the jacket close to front of unit.
The switch can be adjusted by using a flat-headed screw driver and turning it clockwise or counter clock
wise to desired temperature.

IF SURROUNDING AIR IS COLD (EG., under -5 C or 23 F)

TURN THE TEMPERATURE FEELER SO THAT THE HOLES ARE CLOSED OFF AS THE AIR GOES
OVER THE HEAT EXCHANGER, THIS WILL REDUCE FAN CYCLING, UNIT SHUTDOWN, ETC.
(SEE FOLLOWING)

Indoor and outdoor settings of fan switch

Indoors & if surrounding air is warm i.e. -5C/23F-Fan switch should be set to 115°F or higher
so as to shut down unit when heat exchanger is properly cooled, also keeps fan motor

.

from excessive running on when discharging cooler air.

Outdoor-Fan switch should be set between 100°-90°. The colder the temperature the lower

the setting may need to be to prevent fan cycling.

PLEASE NOTE THAT THERE IS A LONGER
TEMPERATURE FEELER ON THE AUTOMATIC HIGH
LIMIT. THIS SHOULD NOT BE ADJUSTED.
