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 building, 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.

•In most cases the infiltration around your uninsulated entry doors and windows will provide enough air flow for efficient heater operation.

HEATER VENTILATION

Unrestricted air flow during heater operation is essential to prevent the area above the installed heater from overheating. 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 additional vent is available from the factory for those having a finished 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 floor).

•Openings equivalent to intake vent would be: partially open doors and partially open windows.

•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 1-866-477-2194.

The selection of the thermostat mounting location is critical to efficient and effective heater operation.

•The thermostat should be mounted about 5 feet above the floor 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 fulfilled, 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 flanged (finished) side on the interior or the exterior of the building or do you want two vents so that both exterior and interior will be finished?) 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 requirements 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 unfinished 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 finished buildings, having the dimensions of the unfinished side of the vent.

5.Install the vent or vents as desired and retain

Model # HS25NG/LP

Installation instructions and Owner’s Manual

with 4 suitable fasteners through the predrilled holes in vent flange.

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” pilot holes into the stud centerline. Use template for simplified 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 diameter) 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” -

20hex nut.

E.Position the heater as shown in Figure 3 and slide the heater mounting clip over the bracket and install the bolt through the clip and bracket.

F.Thread the hex nut onto the bolt and tighten securely.

G.Ensure that the selected thermostat location meets all of the above requirements. Refer to the instructions that come with the thermostat for additional grounding information and mounting instruction.

H.If the wall is of stud and wallboard construction, then use the #6 by 1 inch sheet metal screws, included with the thermostat, and mount the thermostat in the selected location.

I.If wall is brick or masonry, the appropriate anchors must be obtained to accommodate thermostat mounting screws. Use the back plate of the thermostat as a template to mark the hole locations, drill appropriate size anchor holes, install the anchors, securely attach the thermostat using the mounting screws.

J.Connect thermostat wires to gas valve as shown in Figure 4.

3. CONNECTING HEATER TO GAS SUPPLY

WARNING: Depending on local codes and requirements and the installer’s skill level, the sizing and installation of gas lines required to safely and efficiently 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.

3.1Gas Supply Requirements

•See Tables 1 and 2 for gas supply minimum, maximum, 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 MH/HS25NG 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 residential 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 pressure is at least 6” W.C.

WARNING: Model MH/HS22LP is designed to burn liquefied 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 pressure 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 installations 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 assembly. If LP gas is the fuel, ensure that pipe compound is resistant to LP gas. Do not use Teflon™ tape.

USE MODERATE AMOUNT OF PIPE DOPE
