Overview

Thank you for purchasing International Thermal

Research’s (ITR) Expedition space heater.

The Expedition Heater is a vaporizing burner type space

heater with a simple, effective design that produces

radiant heat through the efficient combustion of liquid fuel.

With regular maintenance and proper operation your

heater will function satisfactorily for many years.

The Expedition heat output ranges from 10,000 to 30,000 BTU’s, sufficient to heat

areas such as small warehouses, cabins, workshops, etc.

2.DO’s and DO NOT’s

DO’s

DO determine what heater and exhaust stack installation regulations apply to your

local area. All heaters and exhaust stacks must be installed according to the

standards mandated by the local, state/provincial and federal government

authorities. These standards deal with various matters including heater and flue set

backs and fuel storage.

DO mount the heater securely to a non-combustible floor. If a heater is not solidly

secured and is knocked over, a serious fire hazard could result. Also, ensure that the

heater is level before it is secured down.

DO use clean #1 and #2 diesel fuel only in your heater. If you burn any other fuel or

burn contaminated diesel, you will void your warranty, cause damage to the fuel

control valve and may cause a fire or even an explosion.

DO inspect the entire fuel line to the heater and any connection points for fuel leaks

before firing the heater. The fuel line and connection points must be leak free before

the heater is operated.

DO inspect the space below the burner to make sure there are no blockages and, if

there is any dust or dirt present, it should be removed before operating the heater.

The heater requires oxygen for combustion purposes.

DO inspect the exhaust flue (stove pipe and elbows) to make sure it is secure to the

heater, not blocked, and is leak free.

DO check the draft on the initial setup of the heater by using a draft meter and

ensure the heater is operating under the recommended draft setting. Because of the

unique vaporizing design of the heater, the correct draft is essential for the heater to

operate in a satisfactory manner. If a draft meter is not present, the draft conditions

MUST be estimated. See the details in the manual for estimating the draft conditions.

DO make sure that you have a window or door opened a bit to allow fresh air to

enter the same area where the heater is operating.

DO install carbon monoxide and smoke detectors in the same room as the heater for

safety purposes.

DO NOT’S

DO NOT install the heater or flue unless installation conforms with the regulations

governing your location.

DO NOT use any fuel other than clean #1 or 2 diesel.

DO NOT operate the heater without initially checking the position of the S-tube. During

shipping, the S-tube may become dislodged from the center fuel up tube. View the

position of the S-tube through the glass viewing lid on the top of the heater. If the S-

tube is dislodged, remove the top lid of the heater and reposition the S-tube over the

center fuel up-tube.

DO NOT operate the heater without both a complete exhaust stack in place and correct

draft conditions. Excessive carbon will form in the fuel up-tube and must be cleaned

out for the heater to function correctly.

DO NOT operate the heater in air tight conditions. The heater requires air to operate

and its use will lead to oxygen deprivation in the air tight space. An outside source of air

must be provided to replace the oxygen that is used up by the operation of the heater.

DO NOT operate the heater if you smell smoke or exhaust fumes during its operation.

Shut the heater down immediately and examine the stove pipe for leaks or poor fit.

Repair as required so that all exhaust fumes are vented outside.

DO NOT attempt to relight the heater when it is hot. If the unit is shut down for any

reason, wait until the heater cools down to room temperature before re-firing.

DO NOT leave the heater running unattended. All heaters, regardless of the type or

make, can malfunction and all manufacturers recommend that heaters are not left

running unattended. The Expedition is mechanically capable of operating unattended,

but if there is a malfunction ITR accepts no responsibility or liability for any damage

caused, regardless of the type or extent of the damage. THIS PARAGRAPH

CONTAINS LANGUAGE THAT LIMITS THE MANUFACTURER’S LIABILITY

The Canadian Standards Association (CSA) has some additional consumer tips for space

heaters. Some of those tips are:

DO NOT hang wet clothing above the heater to dry it. The clothing can catch fire as it

dries

DO supervise young children when in the same room as the heater

DO NOT keep gasoline, solvents or other flammable or vapourizing liquids in the same

room as the heater.

More tips can be found on http://www.csa.ca/consumers/consumer_tips/.

3. Components

A) Expedition external components

Heater Shell (1) – The

burner shell assembly is the

area of the heater where

combustion occurs and

contains the perforated

burner shell.

Top Lid (2) – Contains a

sight glass to observe the

flame.

Valve Heat Shield (3) –

Shield between the oil

control valve and burner

shell.

Toby Oil Control Valve (4)

– Located on the side of the

heater and controls the

amount of gravity fed fuel

supplied to the burner.

Turning the control knob will

allow more or less fuel to enter the burner. See sections 5 & 6.

Drain Valve (5) – To fill up the primer cup or to drain fuel from the control valve

Fuel shut off valve (5A) – Opens or closes the flow from the fuel tank to the Oil

Control Valve.

Fuel Connection (6) – 1/4” NPT female threaded fitting

Flue Collar (7) – Attachment for 4” diameter flue stack.

Reamer Tool (8) – To clean the Up-Tube from soot and carbon build up.

Primer Bulb / fuel dispenser (9) – To put priming fuel in the bottom of the

burner base before lighting the heater.

Removable Handle (10) – Used to open the glass lid on the top.

Draft Regulator (11) – To regulate and control the draft.

International Thermal Research 5

B) Expedition internal components

Up–Tube (20) – Receives fuel from the oil control valve and permits fuel vapours to

flow into the S-Tube (25) during operation.

High Fire Ring (21) – Maintains the location of the flames during high fire.

Burner Shell (22) – Area of the heater where combustion occurs. The perforated

Burner Shell contains an up-tube (20) welded to the base of the shell and a

removable, capped S–Tube (25) which sits over the welded up-tube. The Burner

Shell is permanently mounted inside the Heater Shell Assembly (1) and can be

accessed by removing the Top Lid (2).

Burner Base (23) – Bottom of Burner Shell (22).

Burner Heat Shield (24) – Heat shield to keep heat inside the burner Shell and

away from the bottom of the Expedition Unit.

S-Tube (25) – The large capped tube in the center of the perforated Burner Shell is

the S-Tube. The S-Tube is positioned over the welded Up-Tube (20) and is fully

removable. During operation, fuel flows through the Up-Tube (20) where its level is

gravity maintained with the Toby Control Valve (4). Fuel vaporizes due to

combustion heat and is expelled from the up-tube, down through the S-tube and

into the perforated burner shell where it ignites.

Note: If any parts appeared damaged, do not operate the heater. Contact your

authorized Expedition Dealer.

C) Expedition Exhaust kit (Optional) for tents or portable buildings

The exhaust kit for the Trekker comes with eight pieces of 4 inch diameter x 18

inch length flue stack, a rotational rain cap, guy lines, tee, adapter, and elbow.

D.) Expedition Fuel Line kit (Optional) for tents or portable buildings

The Fuel line kit comes with an inline fuel filter, 10 feet of hose, gas cap, siphon

bulb, and fittings to connect to the oil control valve.

4.Installation

A.) Location and Mounting

The Expedition heater must be placed on a flat level surface made of material

that can resist heat. Metal sheet, concrete, etc. are acceptable. The Expedition

must not be mounted on a surface that is not heat resistant.

The surfaces of the heater and the flue stack will be generating heat and should

be taken into consideration when locating and mounting the heater.

The minimum standard clearance between the heater and any building

construction other than the floor is 24 inches (60 cm). The minimum standard

clearance between the exhaust vent pipe and any building construction is 18

inches (45 cm).

A heater which is not level will not operate properly. Adjust the heater so that it

is level in all directions and then securely attach it using screws or bolts through

the 1/4” holes located in the heater legs.

B.) Exhaust Flue Stack

OIL BURNING APPLIANCES MUST BE CONNECTED TO FLUES HAVING SUFFICIENT DRAFT

AT ALL TIMES, TO ASSURE SAFE AND PROPER OPERATION OF THE BURNER.

All heaters and exhaust stacks must be installed according to the standards

mandated by local, state/provincial, and federal government authorities. These

regulations deal with various matters including heater and flue set backs and fuel

storage. You should determine what regulations apply in your local area before

setting up your heater.

The Expedition does not come with an exhaust flue stack. Blue stove pipe or All-

Fuel “L” type vent capable of continuous use for flue gas temperatures up to

1000˚F may be used. Always use a 4 inch diameter, ninety degree elbow off the

heater. The first connection to the heater must be a 90 degree elbow. The non

crimped end of the exhaust elbow is designed to slide over the heater exhaust

International Thermal Research 7

collar. Fix the elbow to the heater collar. Attach a minimum of three feet of the

same 4 inch diameter flue stack to the elbow. After this point, you may transition

into a larger diameter stack. Appropriate parts for the appropriate flue stack can

be purchased at your local heating and ventilation companies. As all installations

differ, it is necessary that you follow all local, state/provincial, and federal

guidelines in selecting the type, method, and location of the exhaust flue stack for

your particular situation.

Before the hook up of the Expedition to a chimney flue stack (4 inch

diameter), check if the chimney is in good condition and that the quality of the

flue pipe will allow sufficient draft.

DO NOT connect horizontal exhaust stacks directly off the heater. The heater

will not operate correctly and will not stay lit. The heater requires a 90 degree

exhaust elbow and a minimum three foot vertical rise before further elbows

and exhaust stack lengths are added. A maximum horizontal length of 3’ is

allowed. Make sure to have a 1/4” slope rise per foot minimum. Each foot of

horizontal length requires 1.5 feet of additional vertical stack height.

The minimum flue stack height for an angled roof with top opening exit and a

vertical only flue stack is 9 feet (2.74 m). For a vertical sidewall exit with a

horizontal run of three feet, the minimum vertical stack height is 13 feet (4 m).

Exhaust location: angled

roof (standard

configuration)

8 International Thermal Research

The chimney flue should extend at least 2’

(0.6 m) above the highest roof surface or

structure within 10’ (3.0 m) horizontally of

the chimney to prevent down drafts.

Install the included draft regulator which is required to maintain stable draft.

DRAFT CONDITIONS All heaters require the proper draft.

If a draft meter is available, set the heater to the recommended water column

reading. The recommended draft for the Expedition is between .040-.060 inches

water column. This is measured 18” (45cm) up the stack, before the draft

regulator, and with the final exhaust stack configuration in place. Follow the

manufacturer’s instruction for the installation, location, and adjusting of the draft

regulator. If a draft meter is not available, estimate the draft (see below).

Exhaust location:

vertical sidewall

(optional) configuration)

Expedition heater with a three foot

horizontal run.

13 feet of vertical stack height in total is

required versus the standard 9 feet.
