Venting

NOTE − The vent is a passageway, vertical or near ly so, used to convey flue gases from an appliance, or it s vent connector, to the outside atmosphere. The vent connector is the pipe or duct that connects a fuel−gas−burning appliance to a vent or chimney.

NOTE − Local codes may supersede any of these provisions.

GENERAL RECOMMENDATIONS AND

REQUIREMENTS

Unit heaters must be vented in compliance with the latest edition of the National Fuel Gas Code (NFPA 54 / ANSI Z223.1) in th e USA and with C SA-B149.1 codes in Canada, as well as applicable provisions of local building codes, and the following instructions.

A stamped/extruded metal transition is supplied with this certified unit. It must not be modified or altered and must be installed on the outlet of the combustion air inducer assembly prior to the installation of the vent connector. Failure to comply with this requirement will void the certification of the unit by the approval agencies.

A single-wall vent connec tor may be used between th e furnace and the vertical vent pipe in all applications; however, single−wall vent material cannot be used

for vertical vent piping in res idential applications. UL−approved Category III venting materials must

be used in all residential applications which include horizontal vent piping.

A single-wall vent pipe used as a vent connector in residential or commercial applications, or as a vertical vent in commercial applications, must have all seams and joints sealed with pressure-sensitive aluminum tape or silicone rubber sealant. Aluminum tape must meet the provisions of SMACNA AFTS-100-73 Standards. The aluminum tape must have a temperature rating of 400°F (204°C). Silicone rubber sealant must have a temperature rating of 482°F (250°C), i.e., Dow Corning

RTV−736 or equivalent.

All joints must be secured with at least two corrosion−resistant screws. All joints must be checked for gas tightness after installation. Single−wall vent pipe used as vertical vent in commercial applications must not pass through any attic, interior wall, concealed space, or floor.

VENTING USING A MASONRY CHIMNEY

The following additional requirements apply when a lined masonry chimney is being used to vent the compact unit heater.

IMPORTANT

heater into a tile lined masonry chimney (interior or outside wall) is prohibited. The chimney must first be lined with either type B-1 vent or an insulated single−wall flexible vent lining system, sized in accordance with venting tables in the ANSI Z223.1, or CSA-B14

1 − Masonry chimneys used to vent Category I units

heaters must be either tile−lined or lined with a listed metal lining system or dedicated gas vent. Unlined masonry chimneys are prohibited. A category I appliance must never be connected to a chimney that is servicing a solid fuel appliance. If a fireplace chimney flue is used to vent this appliance, the fireplace opening must be permanently sealed.

2 − A fan−assisted unit heater may be commonly vented

into an existing lined masonry chimney provided:

a. The chimne y is currently serving at least one

3 − A B-1 double−wall vent or masonry chimney liner

be used as liners, the chim ney must be rebuilt to accommodate one of these methods or some alternate approved m ethod must be found to vent the appliance. When inspection reveals that an existing chimney is not safe for the intended purpose, it shall be reb uilt to conform to nationally recognized standards, lined or relined with suitable

materials or replaced with a gas vent or chim ney suitable for venting unit heaters. The chimney passageway must be checked periodically to ensure that it is clear and free of obstructions.

REMOVAL OF UNIT FROM COMMON VENT

In the event that an existing unit heater is removed from a venting system commonly run with separate gas appliances, the vent ing system is likely to be too lar ge to properly vent the remaining attached appliances. The following test should be conducted while each appliance is in oper ation and the other appliances ar e not in operation, yet remain connected to th e common venting system. If the venting system has been installed improperly, the system must be corrected.

1 − Seal an y unused openings in the comm on venting

system.

2 − Visually inspect the venting system for proper size

and horizontal pitch. Determine there is no blockage or restriction, leakage, corrosion, or other deficiencies which could cause an unsafe condition.

3 − In so far as is practical, close all building doors and

windows and all door s bet ween t he s p ac e i n which the appliances remaining connected to the common venting system are located and other spaces of the building. T urn on clothes dryers and any appliances not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so the y will operate at maximum speed .

NOTE − Local codes may supersede any of the provisions outlined in this instr uc tion.

The FSA series unit heaters use a direct spark ignition system. There is no pilot necessary as the spark lights the main burner as the gas valve is turned on. The direct spark ignition control board emits radio noise as the sparking process is under way. The level of energy may be sufficient to disturb a logic circuit in a microprocessor controlled thermostat. It is recommended that an isolation relay be used when connecting the unit heaters to a microprocessor controlled thermostat. Install the thermostat according to instructions provided. Install a separate fused disconnect switch, with the fuse sized according to blower motor size. Connect wiring through knockout on the junction box located on the side of the unit heater. Refer to heater wiring diagram for connection information. Use 18 gauge wire or larger for thermostat connections.

NOTE − Electrically ground unit in accordance with local codes or, in the absence of local codes, in accordance with the c urrent ed itions of the ANSI/NF PA No. 70, National Electrical Code or CSA C22.1, Canadian Electrical Code, Part 1.

NOTE − Uninsulated ground wires must be wrapped in electrical tape to avoid damage to the electrical system.

Make line voltage connections as shown in figure 7. Connect field wiring as shown on wiring diagram on unit. Also refer to typical diagram in this manual. An additional thermostat wire must be run to terminal G" on heater when continuous blower is desired.

Gas Connection

When connecting gas sup p l y, the len gth of the r u n f r om the meter must be c onsidered in determining the p ipe size to avoid exc essive pressure drop. A line pressure of 7" w.g. (178mm w.g.) for natural gas should be maintained when sizing piping. For correct sizing of piping, consult the utility having jurisdiction.

A drip leg should be insta lled in the vertical pipe run to the unit. In some localities, codes may require that a manual main shutoff valve and union (furnished by installer) be installed external to the unit. Union must be of the ground joi nt type. A drip le g shoul d be readi ly accessible to perm it cleaning and emptying. See figure

To Turn Off Gas to Unit

1 − Set thermostat to lowest level. 2 − Turn off all electrical power to unit if ser vice is to

be performed.

3 − Turn knob on gas valve 90° clockwise to OFF.

Heating Sequence of Operation

1 − When the thermostat calls for heat, the

combustion air inducer starts immediately.

2 − Combustion air pressure switch proves inducer

operation before allowing power to the ignition controller. This switch is factory set and no adjustment is necessary.

3 − After pre−purge of approximately 30 seconds, the

spark ignition is energi zed and the solen oid valves open in the gas valve.

4 − The spark then ignites the gas, the ignition sensor

proves the flame and the combustion process continues.

5 − In the event that th e f lame is not detec ted after the

first 10−second trial for ignition, the controller will repeat steps 3 and 4 an additional two times before locking out the gas valve. Ignition control will then automatically repeat steps 3, 4, and 5 after 60 minutes.

NOTE − To interrupt the 60−minute lockout period, move thermostat from Heat" to OFF" then back to

Heat." Heating sequence then restarts at step 1.

6 − The burners must light without noticeable crossover

delay. There must be no flame lifting from the burner heads, flashback or burning within the burner. The flames should be predominantly blue in color and should be approximately centered in the tubes with no apparent impingement taking place.

7− The ignition control will energize the fan

approximately 45 seconds after ignition is established.

8 − After the thermostat demand is satisfied the gas

valve is closed. Five seconds after the demand is satisfied, the combustion air inducer is shut off.

9 − The ignition control will shut off the system fan

approximately 150 secon ds after the gas valve is de-energized.
