2.2Ventilation Requirements

3.0 Receiving

WARNING

Insufficientventilationmayresultinhealthproblems,carbon monoxide poisoning, or death. Always vent enclosed spaces and buildings according to national, state, provincial, and local codes.

These heaters are the unvented type. Products of combustion generated are released into the space being heated. Sufficient ventilation of fresh air is required to provide adequate air for efficient combustion and to dilute and remove the products of combustion.

In the United States, the minimum intake and exhaust air openings shall provide for not less than 4 CFM per 1,000 BTUH (0.38m3 a minute per kW). In the United States, this may be accomplished by either gravity or mechanical means. Both exhaust fans and inlet air openings are required in tight buildings. Exhaust openings for removing flue products shall be above the level of the heater (ANSI Z223.1/NFPA 54, section 10.18, Infrared Heaters).

Air for combustion, ventilation, and dilution of flue gases shall be obtained by application of one of several methods described in the National Fuel Gas Code, ANSI Z223.1/ NFPA 54, section 9.3, Air for Combustion and Ventilation.

The ventilation technical information outlined in the current ASHRAE Handbooks should be observed when locating vents. When mechanical means are provided to supply and exhaust, a positive interlock with the heater thermostat must be provided by the installer so that the heater cannot operate unless the supply and exhaust system is operating.

Mechanical exhaust fans are typically located at high points of the building. For flat roof areas, a series of small exhausters should be distributed over the roof areas and interlocked with various heating zones. Local codes may permit the use of humidistat control to remove water vapor and products of combustion. Humidistat settings will typically be in the 40 to 55% relative humidity range.

Fresh air intake openings are typically located high on the building sidewalls at or above the level of the heaters. One square inch of net free inlet area per 1,000 BTUH (22cm2 per kW) is required. Multiple inlets, well distributed, should be used and should direct air upward to prevent drafts at floor level. Inlets are typically limited to 1 to 2 square feet (900-1800cm2) in size. Total area required can be computed by dividing exhaust

CFM by 500 feet per minute. (Total area required can be computed by dividing exhaust cubic meters per minute by 152 meters per minute.)

In Canada, the Natural Gas and Propane Installation Code CAN/CSA B149.1 (latest edition) requires the use of mechanical ventilation. The heater shall be provided with mechanical ventilation for combustion and ventilation air:

(1)that is so located that products of combustion from each heater are effectively removed outdoors;

(2)that has a ventilation volume of at least 3 CFM per 1,000 BTUH (0.29m3 a minute per kW) for natural gas and 4 CFM per 1,000 BTUH (0.38m3 a minute per kW) for LP/propane; and

(3)is sufficient to maintain the level of carbon dioxide at less than 5000 ppm measured 6 ft (2M) above the work area.

Check for any damage that may have been incurred during shipment.

4.2 Clearances

This heater model must be mounted with minimum clearances between the combustion surface and combustibles. The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room temperature. Building materials with a low heat tolerance (such as plastic, vinyl siding, canvas, tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer's responsibility to assure that adjacent materials are protected from degradation.

Locate the heater with respect to building construction and equipment so to provide sufficient clearance and accessibility for servicing and cleaning.

WARNING

Single or multi-heater placement must be such that continuous operation of the heater or heaters will not cause combustible materials or materials in storage to attain a temperature in excess of 150°F (66°C). See Hazard Levels, page 2.

WARNING

Under no circumstances should this heater be installed in a combustible atmosphere or in a location where the heater controls can be subjected to ambient temperatures in excess of 150°F (66°C). See Hazard Levels, page 2.

It is recommended that more distance than the minimum clearance be maintained above the unit whether or not the construction is combustible. This will reduce and/or eliminate hot spots and possible staining of painted ceiling surfaces. If the unit must be close to the roof or ceiling, interpose a non-combustible baffle (twice the size of the reflector) between the unit and the roof or ceiling. Allow at least 2" (52mm) between the roof or ceiling and the non-combustible baffle. Allow at least 12" (305mm) between the non-combustible baffle and the top of the heater.

To assure clearances to combustibles are maintained, signs must be posted specifying the maximum stacking height of material under and near the heater.
