The HDG(H) indirect gas-fired air heaters manufactured by BOUSQUET are certified for both indoor andoutdoor installation and designed to serve as a heating system for make-up air or recirculated air. Theyoperate with a minimum thermal efficiency of 80 % and use natural or propane gas. The capacities availablerange from 200 to 5000 MBH (from 59 to 1464 kW) and from 4000 to 90,000 SCFM (from 1888 to 42,475l/s) of air at temperature differences of 50˚F to 120˚F (from 28˚C to 67˚C), which enables flexibility of use formultiple applications.

The multiple pass heat exchanger comprises a primary drum and secondary tubes made of series 304Lstainless steel requiring no thermal treatment to prevent the cracking of welded joints. In addition, series 304Lstainless steel is known for its great resistance to corrosion and high temperatures, which increases the servicelife of the unit. The exchanger is equipped with access panels for the inspection and cleaning of the tubes. It isinstalled as to enable the thermal expansion that occurs during the heating cycles of the unit. The forcedcombustion air and high gas modulation burner with a 20:1 turndown ratio offers optimal heat transfer on allthe surfaces of the exchanger while maintaining optimal combustion efficiency through the entire range ofcapacity.

DESCRIPTIONDESCRIPTION

APPLICATIONSAPPLICATIONS

The heavy duty base frame of the unit is made of structural type U-shaped channels. The walls and roof are made of 18 gauges G90 galvanized steel panels with double folded longitudinal edges. The single wall units are insulated with a one-inch anti-bacterial “Fiber Glass Duct Liner with Reinforced Coating”. The exchanger section is double wall insulated with two inches high temperature “Fiber Glass Blanket” 1.5lb/pi3 density, and covered with a 22 gauge G90 galvanized steel liner. The weatherproof control cabinet has one large access door to allow for the maintenance of the gas piping and electrical components. The exterior surfaces of the unit are treated with a phosphate cleaner-conditioner and covered with a synthetic Chromating Phosphate with anticorrosive primer. The finish is ensured with first quality high performance alkyd resin enamel. When required, a fresh air intake cowl, a mixing box with filters, motorized damper, or downturn or upward discharge plenum may be incorpo-rated into the HDG(H) unit. HDG(H) heaters are CETLUS approved and are certified according to standards CAN/CGA3.2 and UL 795.

INSTALLATION GUIDELINESINSTALLATION GUIDELINES

The installer of a heater such as the HDG(H) must follow certain rules in order to comply with thecodes governing gas equipment. Here are some recommendations:

• When gas pressure exceeds 1/2 psig (3.5kPa), a high pressure regulator must besupplied and installed by the contractor. This regulator must have the same modulationcapability as the burner (20:1 turndown).

• Allow for sufficient clearance around the unit to enable its installation and maintenance.

For indoor installation,

• all purge and regulator vents must be individually piped to the exterior according to codeCGA-B149 or other codes in effect;

• the chimney must satisfy the following requirements:• have double walls• be certified for positive pressure units (type PS)• be certified ULC/UL;

• ensure that there is enough air for the combustion in the room where the heater is installed(refer to code in effect);

• ensure that the combustion air is clean and free of dust or corrosive material that couldreduce the service life of the unit.

• For chimney and breeching dimensions, consult the manufacturer.

For any other information related to the installation of the HDG(H) air heaters, refer to theinstallation and service manual pertaining to these units.
