7 ELECTRICAL CONNECTION (a) Burner/Control Internal Wiring IMPORTANT: All electrical work should be done by a qualified electrician in accordance with the National Electrical Code ANSI/NFPA 70. Supply: 120 V, 60 Hz, single phase Current Rating: 0.3 amp max 2319 Laurelbrook Street, Raleigh, NC 27604 · (800) 542-7221 · FAX (919) 834-4526 · -10 A. 7 ELECTRICAL CONNECTION (CONT.) The electrical supply to the heater is by three wires: live, neutral and ground connections. It is recommended that the supply cable be in metallic conduit to the 3/4'” hole provided. Power is ONLY supplied to the terminal in the back of burner as shown below: Power is supplied to fan through the knock out on the side of the burner housing. Fan leads should be connected to the burner leads using the wire nuts provided. Connect yellow/green wire from fan, to green wire of the burner, connect either black wire from the fan, one to the white and one to the black/brown of burner. Insure that conduit clamp is firmly tightened. It is recommended that the electrical circuit controlling the heater or group of heaters include thermostats, a time switch and if required manual control switches. All such controls and switch gear must be rated to handle the total inductive load of the circuit they control. For large installations, the use of relays or contractors should be considered. Control panels are available from the manufacturer incorporating multiple Black Bulb Thermostats controlling up to 10 heaters per thermostat for zone control of the heated area. Typical External Wiring is shown in diagram. (Control panels are not A.G.A. design certified.) 2319 Laurelbrook Street, Raleigh, NC 27604 · (800) 542-7221 · FAX (919) 834-4526 · -11 A. 8 VENT REQUIREMENTS AND DETAILS (1) UNVENTED UNITS: Heaters may be installed without a flue providing the governing building codes are met and that consideration is properly given to possibilities of condensation on cold surfaces. Installation shall meet the following requirements when unvented: (A) Internal volume of the heated room must be greater than 214 cu. ft. per 100 BTU/HR of heaters installed. (B) Natural or mechanical means shall be provided to supply and exhaust at least 4 CFM per 1,000 BTU per hour input of installed heaters. (C) Combustion gases shall not impinge on combustible materials with a temperature in excess of 150° F. (D) The blower discharge must be horizontal. (2) VERTICAL VENTING: The heater may be installed with a vertical flue. A down vent elbow must be fitted to the induced draft fan exhaust outlet, which should be rotated to a vertical position. A vent elbow designed to accept a 6 -inch nominal sheet metal flue pipe is available as an optional extra. All flue piping should be adequately supported from the building structure and terminated with an approved terminal. The maximum flue length is 30 ft. with a maximum of two bends. All connections should be properly sealed. Generally, terminal may be located horizontally a dimension equal to its vertical dimension. (3) HORIZONTAL VENTING: Individual units may be vented horizontally through side walls. Venting must be installed in accordance with ANSI Z2223.1 (NFPA-54) and local codes. Maximum length of vent is 25 ft. with 2-90 degree long radius elbows. Runs of 12 ft. or shorter can use 4-inch diameter flue with Ultimate Products part number V0200. Runs over 12 ft. should use 6-inch dia. flue pipe.Any portion of flue that passes through a combustible wall must be insulated or use an approved insulating thimble. Recommended parts are Ultimate Products’ (Part # V-0200) for 4-inch flue and (Part # V-0800) for 6-inch flue. Standard vent terminals must extend at least 6-inches from the wall and at least 24-inches from any combustible overhang. Protect the building material from degradation by flue gases. 2319 Laurelbrook Street, Raleigh, NC 27604 · (800) 542-7221 · FAX (919) 834-4526 · -12 A. 8 VENT REQUIREMENTS AND DETAILS (CONT.) Flue joints should be sealed using RTV high temperature sealant and secured using at least three (3) sheet metal screws. Should condensation occur flue should be shortened or insulated. The terminal must exit the building at least 7 ft. above any area accessible to the public. The terminal must be at least 3ft. away from any air intake to the building. If the heater is equipped with ducted combustion air, the terminal must be at least 3 ft. away from the air inlet and located higher than the inlet. The vent terminal must be protected from blockage by snow. A.9 FRESH AIR DUCTED INTAKE Whenever the heater is installed in locations where air born dust or other polluted atmosphere is present; a fresh air supply should be ducted to the burner. A heater modified for fresh air intake should be specified when ordering. This model is modified with a 4-inch diameter duct connection at the burner. A fresh air duct of 4-inch diameter should be install...
