Unlike direct combustion heaters, which send

combustion products into the space with hot

air, These HEATSTAR PRO indirect-fired keep

combustion products separated from clean hot

air by means of a heat exchanger. As combustion

occurs in the combustion chamber, combustion

by-products escape through the chimney

and away from the user through the options

described in “FRESH AIR AND VENTILATION” on

page 5. A fan blows clean ambient air across

the outside of the combustion chamber which

warms the air as it is pushed toward the space.

AIR INTAKE

A rough estimate of minimum opening for

ventilation to support heater operation is 1in²

for each 1,000 BTU of the heater. Please refer to

Table 3 to determine the approximate minimum

required opening for ventilation of the space

containing the heater unit.

OPERATION

BEFORE SWITCHING HEATER ON

Before any attempt of starting the heater

is made, familiarize yourself with warnings,

specifications and precautions page 2 - 4.

• Check that the fuel is appropriate. Check

that there is sufficient fuel in the fuel tank by

reading the fuel gage embedded near the fuel

filter. If not already closed, close the tank cap

by rotating it clockwise. It is recommended

to use winter diesel oil below ambient

temperatures of 41 °F.

• Check that minimum safety clearances from

combustibles, listed in “CLEARANCES TO

COMBUSTIBLES” on page 3, is achieved in

all directions.

• Make sure that flue gas is adequately

ventilated from the chimney, refer to “FRESH

AIR AND VENTILATION” on page 5.

• Attach a duct to the outlet if directed venting

of output clean hot air is desired. Ducting can

be installed with the specific clamp or quick

coupling. Refer to “ACCESSORY CHART” on

page 18 for the correct Duct adapter.

• Check that your electrical supply and any

extension cable can meet the requirements

listed in the specifications table.

WARNING: Not suitable for use on wood

floors or other combustible materials.

TURNING ON THE HEATER

Refer to Figure 5 for the layout of the control

panel. The heater turns on by flipping the power

switch from “OFF” to “ON”. The burner box will

begin firing, which will heat up the combustion

chamber. Within 30 seconds the blower fan will

activate.

THE EXTERNAL THERMOSTAT SOCKET

The heater can only work automatically when a

control device, such as a thermostat or a timer,

is connected to the heater. F105106, a 16ft

digital Thermostat, and F105108, a 32ft analog

thermostat are both approved for use by the

manufacturer with HSP100ID, HSP200ID, and

HSP300ID. Connection to the heater is made

by removing the thermostat socket cap and

connecting the room thermostat to the socket.

If no room thermostat will be connected the cap

must be inserted into the socket.

SWITCHING OFF THE HEATER:

The heater turns off by flipping the power switch

from “ON” to “OFF”. The burner box will turn

off, and the fan will continue running to cool

off the burner box. Do not unplug the heater

until this cooling cycle has totally ended.

This may take up to 5 minutes. Once the heater

has completely cooled down and the unit is

unplugged, ensure that the fuel tank cap is

properly closed to prevent fuel leakage during

transport and/or storage. To keep the heater

in the best possible conditions, store the heater

in a dry and safe place after carrying out the

procedure in ”CLEANING THE FUEL TANK” on

page 8.

light it means the heater needs to be reset. To

reset the heater, press the reset button all the

way down. Identify and remove the cause that

stopped the appliance (for instance, obstruction

of air intake and/or outlet, obstruction to the

free rotation of fan, etc.). Please contact an

appointed service center for assistance.

MAINTENANCE

WARNING:

Never service heater while it is plugged in,

operating or hot. Severe burns or electrical

shock can occur.

Adherence to “PREVENTATIVE MAINTENANCE

SCHEDULE” on page 8 will ensure a long

trouble free life to your heater.

For user convenience, adjustment of heater’s

foot frame can reposition the wheels along

the direction show in Figure 6. Only adjust the

wheels when the heater is on a level surface,

supported by means other than the foot frame,

and the fuel tank is empty. Adjust the wheels

by removing the screws and nuts which secure

the foot frame to the heater, slide to foot frame

such that the wheels are in Position 1 or Position

2, and secure again. Position 1 allows easy

movement with an empty or half full fuel tank.

If the heater will be subjected to substantial

movement with a full tank, move the wheels

2.75 inches (7cm) to be in Position 2.

SAFETY THERMOSTAT

The high limit safety thermostat blocks machine

operation when malfunctioning occurs. The

safety thermostat is normally a closed electrical

switch.

FLAME CONTROL EQUIPMENT

The electronic control box coordinates the

operation between the fuel solenoid valve,

which blocks or allows flow of fuel to the spray

nozzle, and the photocell, which detects the

light intensity (or absence) of a flame. The

coordination of flame brightness and fuel control

allows for stable flame conditions.

ELECTRODES

Fastened directly on the plate of the combustion

chamber, the generated spark between

electrodes ignites the fuel mixture. To ensure a

proper arc between electrode tips maintain the

following distances illustrated in figure 7 below;

between the nozzle and electrodes (left) and the

electrode tips (right):

A = 0.11 inches,

B = 0.23 inches,

C = 0.11 inches

TRANSPORTATION

FIGURE 7: ELECTRODE POSITIONS

IN ORDER TO KEEP THE HEATER IN THE BEST

POSSIBLE CONDITIONS, WE RECOMMEND

FOLLOWING THE PROCEDURE BELOW:

• Clean the fuel tank by the method described
