Dayton High-Intensity Heaters

Description

Dayton high-intensity heaters become highly efﬁcient generators of infrared radiation by heating a ceramic refractory material to incandescence. The principal operation is to pass a gas-air mixture through a perforated ceramic refractory, and ignite it on the refractory surface. This causes the ceramic material to be heated to approximately 1780°F and generate large amounts of infrared radiation that may be directed anywhere heat is desired. Infrared radiation heats people and objects it strikes and not the intervening air. Included is a direct spark ignition system, manifold pressure tap, porous ceramic grids, a polished aluminum reﬂector and a chain set for hanging the heater. Typical applications are loading docks, warehouses, service garages, factories, aircraft hangars, etc.

WARNING

Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or death.

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

This heater must be installed and serviced by trained gas installation and service personnel only. Failure to comply could result in personal injury, asphyxiation, death, ﬁre and/or property damage.

WARNING

Not for residential use!

This heater is not approved in any

quarters, attached garages, etc. Installation in residential indoor spaces may result in property damage, serious injury or death.

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.

Design

To ensure a safe, properly designed heating system, a layout should be developed for the correct placement of the infra-red heater(s). Aside from safety factors such as clearance to combustibles (see Chart 1.1 on page 5), you should take 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 infra-red 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 infra-red 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 futher than the recommended distance (see Figure 2.1 ).

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

Factory recommended mounting heights (see Chart 2.2) are listed as a guideline. If infra-red heaters are mounted too low or too high, they may result in discomfort or lack of heat. The factory generally recommends observing the recommended mounting heights to optimize comfort conditions. However, certain applications such as spot heating, freeze protection, outdoor patio heating or very high ceilings may result in the heaters being mounted outside of the recommended mounting heights.

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.

Potentially ﬂammable substances, such as Propylene Glycol or antifreeze solutions, are not to be used in conjunction with this heater.

For further information consult NFPA 13. Always observe applicable state and local codes.

WARNING

Improper ventilaton may result in

E N G

It is required that the upper levels of the space to be

heated are 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 infra-red 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.

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 4.0 CFM per 1000 BTU/H of natural gas consumed must be provided. If propane is used, a positive air displacement of 4.5 CFM per 1000 BTU/H of propane 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 gravity 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.

equipment malfunctions, condensation and other air quality issues.

Figure 2.6 Hot Flue Discharge

Flue discharge Important! Do not

install gas piping or electrical wiring above the ﬂue discharge area!

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 1000 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.

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.

Ventilate enclosed spaces and buildings according to national, state, provincial and local codes. Failure to provide adequate ventilation may result in

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.

WARNING

An approved connector, suitable for the environment of equipment usage, is required. Visible or excessive swaying,

ﬂexing and vibration of the gas connections must be avoided to prevent failure. Neither the gas pipe nor the connector shall be placed in the ‘ﬂue discharge area’.

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.

The installation of this heater must conform with local building codes or, in the absence of such codes, the National Fuel Code (NFPA 54).

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.

1. 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).

2. 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.

3. 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

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

4. Attach the ﬂexible connector to the adapter and burner control box inlet. Seal the joints.

NOTE: Excessive torque on the manifold may

misalign the oriﬁce. Always use two wrenches to tighten mating pipe connections.

5. Final assembly must be tested for gas leaks.

24 VAC. 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.

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

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.

Lighting Instructions

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

position.

2. Close electrical circuit (typically the thermostat).

3. If the heater fails to light, turn off gas, open

electrical circuit and wait 5 minutes before repeating the above steps.

Shutdown Instructions

1. Open electrical circuit.

2. 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 proceding to hard lockout. The control can be reset by brieﬂy interrupting the power source.

WARNING

Do not atempt to ignite heater by hand. Failure to comply could result in personal injury, property damage, explosion, ﬁre or death.
