CLEARANCES

E6 Installation instructions and Owner’s Manual

•This heater may be mounted on any wall;

however, it is recommended that the heater be

mounted in the middle of the wall opposite any

overhead doors.

•When selecting installation locations for this

heater ensure that the opening of any exterior

or interior doors or windows will not violate

minimum clearances or contact any heater

components.

•If an overhead door is installed in the build-

ing, verify that the heater is not installed in

such a way as to interfere with door operation

and verify that the door in its open position

will not reduce clearances below the minimum

requirements. Never mount the heater in such

a way that would position the heater above an

opened overhead door.

Unrestricted air ow during heater operation is essen-

tial to prevent the area above the installed heater from

overheating. In most cases the infiltration around your

uninsulated entry doors and windows will provide

enough air flow for efficient heater operation. If your

workshop/utility building is tightly insulated (including

windows, doors, openings, etc.) the following

ventilating methods must be followed:

•A single exhaust vent is supplied with your

heater for your convenience. This vent must

be located above the heater (preferably at the

highest point in the building interior) and it must

vent to the exterior of the building. An addition-

al vent is available from the factory for those

having a nished workshop or utility building.

•An intake vent, or equivalent, from the exterior

of the building and having an effective area of

75 square inches must be located below the

heater (preferably within 2 feet of the building’s

oor).

•Openings equivalent to intake vent would be:

partially open doors and partially open win-

dows.

•Openings of this size (5 inch by 13 inch, or 3

inch by 25 inch) will prevent dangerous heat

buildup above the heater.

Ensure that no gas lines or electrical wiring or conduits

will interfere with mounting of the heater to the wall.

Depending on local codes and requirements and the

installer’s skill level, the sizing and installation of gas

lines required to supply the heater may require the

assistance of a professional. If in doubt as to these

requirements, discuss the requirements of this manual

with the dealer from whom the heater was purchased

and your gas supplier, or call our customer service

department at 1-800-251-0001.

The selection of the thermostat mounting location is

critical to efcient and effective heater operation.

•The thermostat should be mounted about 5 feet

above the oor where air can circulate freely

around it.

•The thermostat should not be mounted directly

to a cold exterior wall without an insulated

mounting block.

•The thermostat should not be mounted in direct

drafts.

•The thermostat should not be mounted directly

below the installed the heater.

•The thermostat should not be installed at a

distance that is farther from the heater than the

length of the thermostat cable.

2. HEATER MOUNTING INSTRUCTIONS

After selecting the heater installation location and the

thermostat location and after verifying and ensuring that

all of the above placement requirements are fullled,

mount the heater as follows:

A. Determine how you wish to install the vent based

on the construction of the building and your

personal preference. (i.e., do you wish the anged

(nished) side on the interior or the exterior of the

building or do you want two vents so that both

exterior and interior will be nished?) If needed,

order an additional vent from the factory. Our

address and toll free phone number are on the rear

cover of this manual. Install the vent as follows:

1. See Figure 3 for dimensions and information on

the vent.

2. Select a place as high above the heater as

possible in accordance with the above require-

ments and ensure that the vent or vents will

not contact or interfere with existing building

systems (i.e., ducts, wiring, plumbing, etc.)

3. Place the unnished side of the vent against

the wall in its elected location and trace its

dimensions on the wall with a pencil or other

suitable marker.

4. Cut or otherwise open a hole in the wall, or

walls for nished buildings, having the dimen-

sions of the unnished side of the vent.

5. Install the vent or vents as desired and retain

HEATER VENTILATION

E7 Installation instructions and Owner’s Manual

with 4 suitable fasteners through the predrilled

holes in vent ange.

B. Prepare to install the heater wall mounting bracket

as follows:

1. If the wall mounting bracket is to be attached to

a stud and wallboard wall, refer to Figure 3 for

dimensions, locate a stud, and drill two 1/8” pi-

lot holes into the stud centerline. Use template

for simplied installation.

2. If the wall mounting bracket is to be attached

to a brick or masonry wall, refer to Figure 3 for

dimensions. Obtain two 1/4 inch (inside diam-

eter) expansion anchors and determine the

correct drill size to be used with them. Drill the

appropriate size holes in the brick or masonry

to accept the anchors.

C. Place the wall mounting bracket on the wall and

align the two through holes on the bracket with

the pilot holes or anchors. Install 1/4 inch by 2-1/2

inch lag screws through the bracket into the stud or

anchors. Tighten securely.

D. Locate heater mounting clip on back of heater and

select the 1/4” – 20 by 3/4” hex head bolt and 1/4” -

20 hex nut.

3.1 Gas Supply Requirements

•See Tables 1 and 2 for gas supply minimum, maxi-

mum, operating, and manifold pressures for both

heater models. Pressures are provided in inches of

W.C. (water column). Also, see heater rating plates

located on the heater.

WARNING: Model MH25NG is designed to burn

natural gas and it comes equipped with a regulator.

The regulator is built into the gas valve. The maximum

inlet pressure to this regulator is 1/2 psi (14 in. W.C.) If

gas line pressure exceeds 1/2 psi, then an additional

regulator must be installed before the heater/regulator

to step down the pressure to a maximum of 1/2 psi.

•Most non-commercial natural gas services provide

a line pressure of 4 oz. (6.9 in. W.C.). If in doubt

consult your natural gas supplier.

•To ensure the best performance from your natural

gas heater make sure the supply manifold pres-

sure is at least 6” W.C.

liqueed petroleum (LP) gas and it comes equipped

with a regulator. The regulator is built into the gas

valve. The maximum inlet pressure to this regulator

is 1/2 psi (14 in. W.C.). If gas line pressure exceeds

1/2 psi, then an additional regulator must be installed

before the heater/regulator to step down the pressure

to a maximum of 1/2 psi.

• To ensure the best performance from your LP gas

heater, make sure the supply manifold pres-

sure is at least 1/2 psi (14 in W.P.).

3.2 Piping Requirements

All piping installed must comply with local codes and

ordinances or with National Fuel Gas Code,

ANSI Z223.1 (NFPA 54), whichever takes precedence.

When installing piping, the following requirements

must be taken into consideration: Canadian installa-

tions must comply with the B149.1.2 Gas Code.

•Use new properly reamed black pipe free from

chips.

•Apply a good quality pipe compound to all

male threads as shown in Figure 5 prior to as-

sembly. If LP gas is the fuel, ensure that pipe

compound is resistant to LP gas. Do not use

Teon™ tape.
