2.0 Installation

WARNING

Read and understand, the installation, operating and maintenance instructions thoroughly before installing or servicing this equipment.

Only trained, qualiﬁed gas installation and service personnel may install or service this equipment.

CAUTION

This heater cannot be used in a building with an uninsulated roof or condensation problems can occur.

Design

To ensure a safe, properly designed heating system, a layout should be developed for the correct placement of the infrared heater(s). Aside from safety factors such as clearance to combustibles (see Chart 1.1 on page 5), you should take also into consideration the environment (e.g., cold/drafty, average, protected), heat coverage (sq. ft.) needed, heater centers, the distance behind a person or work station(s) and exhaust path. Also, the effective infrared surface temperature of a person or object may be diminished with wind above 5 mph. Wind barrier(s) may be required. Most importantly, clearance to combustibles must always be maintained! Refer to hazards on page 4.

This installation manual, along with national, state, provincial and local codes, address these issues. It is critical that you read, understand and follow all guidelines and instructions. Always inspect and evaluate the mounting conditions, space for exhaust, gas supply and wiring.

Perimeter mounting of infrared heaters provides the most effective distribution of heat. The recommended spacing between the heaters is shown in Chart 2.1. Add additional heaters in the center of the space when heaters are spaced farther than the recommended distance (see Figure 2.1 ).

When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits, formaldehydes, etc.) can evaporate. This may result in odors or fumes being emitted into the environment. To correct this problem, clean the area and/or introduce additional ventilation. Heaters installed and serviced in accordance with the installation manual do not emit foul odors into the environment.

IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater. This distance may exceed the published clearance to combustibles. Certain applications will require the use of high temperature sprinkler heads or relocation of the heaters.

Sprinkler systems containing propylene glycol or other ﬂammable substances are not to be used in conjunction with this heater without careful consideration for and avoidance of potential ﬁre or explosion hazards. For further information consult NFPA 13. Always observe applicable state and local codes.

Heater Mounting

WARNING

Improper suspension of the infrared heater may result in collapse and being crushed. Always suspend from a permanent part of the building structure that can support the total force and weight of the heater.

Failure to maintain minimum clearance to combustibles may result in ﬁre and/or explosion, property damage, serious injury or death. Always maintain minimum clearances and post signs or provided tags (F/N: LL01) where needed. Signs should state the hazards for the particular application and be legible to the building occupants. Consult the factory or a factory representative for additional information on signage compliance.

The heater can be suspended with chains or rigid threaded rod. Local codes, or conditions that would cause the unit to move (e.g., wind drafts, blowers, crane rails, etc.), may require rigid threaded rod. Consult all applicable codes before installation.

The heater must be level from side to side and between 20° and 35° from horizontal. The pilot burner or ignitor, manifold and controls must be located on the lower end. Refer to ﬁgures 2.3 and 2.4.

DR Series Manual

Ventilation

WARNING

Insufﬁcient ventilation may result in health problems, carbon monoxide poisoning or death. Vent enclosed spaces and buildings according to

national, state, provincial and local codes.

Improper venting may result in asphyxiation, ﬁre, explosion, injury or death.

It is required that the levels where heaters are mounted be properly ventilated to supply combustion air to the heaters and to sufﬁciently dilute the products of combustion. It is also required that the ﬂue discharge area is kept clear of gas piping and electrical wiring (see Figure 2.6).

This infrared heater must be vented in accordance with national, state, provincial and local codes and the guidelines in this manual. In the United Sates refer to the latest edition of ANSI Z223.1 (NFPA 54) and in Canada refer to the latest edition of the CAN/CGA B149.2 Standard.

Figure 2.6 • Hot Flue Discharge

Flue Discharge Area

Important! Do not install gas piping or electrical wiring above the ﬂue discharge area!

20˚ - 35˚

SIDE VIEW

Provisions must also be made to provide sufﬁcient fresh air intake area and exhaust air outlet area. For proper ventilation, a positive air displacement of 4 cfm/1,000 BTU/h of gas consumed must be provided.

Where insufﬁcient air movement exists, induced air displacement is required. A balanced system is essential to avoid negative building pressure which causes excessive inﬁltration, unfavorable drafts and affects combustion efﬁciency.

Air displacement may be accomplished by either natural or mechanical means. Mechanical exhausters are preferred and typically mounted at high points on the roof where stagnant air accumulates inside the building. For a ﬂat roof, considerations of prevailing winds, high and low pressure areas, and distribution of air movement must be taken into consideration when locating exhausters.

Best air distribution is accomplished by using a number of small exhausters versus one large exhauster. Provide a minimum of one square inch of inlet area per 1,000 BTU/h for combustion air supply. Inlet opening in the building should be well distributed (see Figure 2.1) high in the sidewalls and should direct incoming air upward to dilute products of combustion while preventing drafts at lower levels. Inlets are typically 1 to 3 sq. ft.

Manifold/Control End Down

Local codes may require that mechanical exhaust systems be interlocked with heaters to enable both to function simultaneously (see page 17, Figure 2.7) or allow control of exhausters with a ceiling mounted humidistat.

DR Series Manual

2.0 Installation • Gas Supply

Gas Supply

WARNING

Improperly connected gas lines may result in ﬁre, explosion, poisonous fumes, toxic gases, asphyxiation or death. Connect gas lines in accordance to national, state, provincial and local codes.

The gas supply to the infrared heater must be connected and tested in accordance with national, state, provincial and local codes along with the guidelines in the Detroit Radiant DR Series manual. In the United States refer to the latest edition of the ANSI Z223.1 (NFPA 54) Standard and in Canada refer to the latest edition of the CAN/CGA B149.2 Standard.

Important! Before connecting the gas supply to the infrared heater(s):

• Check that the gas piping and service has the capacity to handle the load of all heaters being installed, as well as any other gas appliances being connected to the supply line.

• Check that the main gas supply line is of proper diameter to supply the required fuel pressures.

• If utilizing used pipe, verify that its condition is clean and comparable to a new pipe. Test all gas supply lines in accordance with local codes.

• Test and conﬁrm that inlet pressures are correct. Refer to the rating plate for required minimum and maximum pressures (see Chart 2.3). The gas supply pipe must be of sufﬁcient size to provide the required capacity and inlet pressure to the heater (if necessary, consult the local gas company).

2.0 Installation • Gas Supply

DR Series Manual

WARNING

The gas outlet must be in the same room as the appliance and accessible. It may not be concealed within or run through any wall, ﬂoor or partition.

Install a sediment trap / drip leg if condensation may occur at any point of the gas supply line. This will

decrease the possibly of loose scale or dirt in the supply line entering the heater’s control system and causing a malfunction. Note: High pressure gas above 14 in. W.C.P. (water column pressure) requires a high pressure regulator and ball valve (ﬁeld supplied).

Form the stainless steel ﬂexible connector (ﬁeld supplied) into a smooth C-shape allowing 12 in.

between the ﬂexible connector’s end nuts. Figure 2.5 on page 13. NOTE: Not for use on rigidly mounted heaters.

Attach the ball valve (ﬁeld supplied) to the gas supply pipe. Apply pipe compound to NPT adapter

threads to seal the joint. Use only a pipe compound resistant to liquid petroleum. NOTE: Provide a 1/8 in. NPT plugged tapping accessible for test gauge connection immediately upstream of gas connection to the heater (provided on ball valve, when supplied).

CAUTION

The ﬁttings (nuts) on the ﬂexible connector must be connected to an adapter. They may not be directly connected to the gas supply pipe.

Attach the ﬂexible connector to the adapter and gas inlet. Seal the joints.

Note: Excessive torque on the manifold may misalign the oriﬁce. Always use two wrenches to tighten mating pipe connections.

WARNING

Testing for gas leaks with an open ﬂame or other sources of ignition may lead to a ﬁre or explosion and cause serious injury or death. Test in accordance with NFPA or local codes.

Final assembly must be tested for gas leaks according to NFPA or local codes.

In high moisture or corrosive environments, use gas supply lines and connectors suitable for the environment. Periodically inspect for signs of failure or leakage.

CAUTION

DR Series Manual

2.0 Installation • Electrical

Electrical

WARNING

Electric Shock

Field wiring to the heater must be connected and grounded in accordance with national, state, provincial, local codes and to the guidelines in the this manual. In the United States refer to the most current revisions to the ANSI/NFPA 70 Standard and in Canada refer to the most current revisions the CSA C22.1 Part I Standard.

Control systems are initiated by either 120 VAC, 24 VAC or millivolt energy. The 120 VAC systems can be used directly from a 120 VAC line. On 24 VAC systems, transformers must be used to supply power of sufﬁcient VA rating for single or multiple connected installations.

Important! Proper grounding and polarity are essential for heaters with spark ignition controls. If the system is not properly grounded, it cannot determine the presence of a ﬂame and will lockout and shut off.

Millivolt systems require NO external power, as energy needed to operate the valve is developed by the power-pile generator. Do not use multiple connections, as one thermostat may only control one heater.

For wiring of controls on the unit see the wiring diagram included on page 18. It is recommended that the thermostat be installed on the hot side of a fused supply line and have a sufﬁcient ampere capacity rating for the heater(s) it will control. The ventilation system may be controlled separately from the heating system (consult local codes) by the use of a humidistat that closes when the humidity rises. The humidistat control should be installed at roof level. For summer ventilation, a simple on/off switch can be installed at the occupant level.

3.0 Operation • Lighting Instructions

3.0 Operation

WARNING

Do not attempt to ignite a direct spark ignition heater by hand. Failure to comply could result in personal injury, property damage, explosion, ﬁre or death.

Upon satisfactory completion of the electrical supply and purging of the gas supply line to the heater(s),

follow the lighting instructions on the heater’s rating label to put the heater into operation.

Direct Spark Ignition (NFS-2 / PFS-2)

Lighting Instructions

Rotate the heater’s valve knob to the “ON” position.

Close electrical circuit (typically the thermostat).

If the heater fails to light, turn off gas, open electrical circuit and wait 5 minutes before repeating the

above steps.

Shutdown Instructions

Open electrical circuit.

Rotate the heater’s valve knob to the “OFF” position.

Sequence of Operation

Starting Circuit: Upon a call for heat, voltage is applied to L1 and Neutral. After a pre-purge, the spark

electrode is energized and the gas valve opens. The trial for ignition is 15 seconds. If ﬂame is not sensed, the heater will attempt two more times to reignite.

Running Circuit: After ignition, the sensing electrode monitors the burner ﬂame. If sense of ﬂame is lost, the control immediately acts to reignite the gas-air mixture. If ﬂame sense is not established within 15 seconds, the heater will attempt two additional ignition sequences before proceeding to hard lockout. The control can be reset by brieﬂy interrupting the power source.

Millivolt (NMV-2 / PMV-2)

Lighting Instructions

Purge main gas supply line.

Slightly depress and rotate the heater’s manual gas valve knob COUNTERCLOCKWISE from the

“OFF” position to the “PILOT” position.

Fully depress the manual gas valve knob and light the pilot burner. Continue to depress for 30

seconds and then release.

Rotate the heater’s valve knob to the “ON” position.

Close the control circuit. If the heater fails to light, turn off the gas, open control circuit and wait 5

minutes before repeating the above steps.

Shutdown Instructions

Open the control circuit.

Rotate the heater’s valve knob to the “PILOT” position, depress slightly and rotate to the “OFF” position.

Sequence of Operation

Starting Circuit: After manually lighting the pilot (see lighting instructions), upon a call for heat, the main

burner solenoid is energized. The gas valve opens and the pilot lights the main burner.

Running Circuit: After ignition, the powerpile monitors the pilot ﬂame. If the pilot ﬂame is lost, the powerpile cools and closes the valve within 180 seconds. See lighting instructions to relight the heater.
