Positioning and Setup
Some form of mechanical assistance will be required to position these broilers, as the smallest weighs 338 lbs
(153 kg) and the larger sizes weigh 620 lbs (281kg).. A pallet or lift jack will also make leveling easier, as these units are designed to sit flush on a counter, do not have adjustable legs or feet, and leveling is with shims and repeated fitting..
Inside the unit, the char-broilers use cast tubular burners with cast iron radiants, which are secured to the burner hangers to stop vibration and damage during shipping Once free, double-check that the burners are positioned squarely in the notches of the back burner holder.. If they are out of position, the burner will not work properly..
Air Supply and Ventilation
The area around the appliance must be kept clear to avoid any obstruction to the flow of combustion and ventilation air, as well as, for ease of maintenance and service..
Means must be provided for any commercial, heavy-duty cooking appliance to exhaust combustion waste products to the outside of the building.. This is doubly important for open grate broilers, since the design promotes grease and fat dripping through onto hot radiants sending smoke back up onto the product as seasoning.. This smoke then continues either up to the ceiling or to an exhaust hood.. Garland Char-Broilers must be under a vent hood! Filters and drip troughs should be part of any industrial hood, but consult local codes before constructing and installing a hood..
Air movement should be checked during installation, strong exhaust fans in the hood or in the overall system can produce a vacuum in the room and/or cause air drafts.. Either of which can interfere with the burner performance and be difficult to diagnose.. If burner problems persist, make-up air openings or baffles may have to be provided in the room.. Any adjustments to air movement should be performed or inspected by a qualified technical installer.. Maintain and do not block the appliances designed air openings..
Gas Connection
NOTE: The gas supply (service) line must be the same size or greater than the inlet line of the appliance.. Garland Char- Broilers use a 3/4” NPT inlet.. Sealant on all pipe joints must be resistive to LP gas..
The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3..45 kPa)..
The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3..45 kPa)..
Manual Shut-Off Valve
The Manual Shut-Off Valve is supplied by the installer, it must be installed in the gas service line ahead of the appliance and regulator in the gas stream and in a position where it can be reached quickly in the event of an emergency..
Pressure Regulator
All heavy-duty, commercial cooking equipment must have a pressure regulator in the incoming service line for safe and efficient operation, since service pressure may fluctuate with local demand.. The manual shut-off valve is normally supplied by the installer, but pressure regulators are shipped from Garland with every Char-Broiler..
Regulators are pre-set at the factory for 4”WC (natural gas) or 10”WC (propane) according to the customer’s ordering instructions.. Adjust regulator to manifold operating pressure as per rating plate..
Prior to connecting the regulator, check the incoming line pressure, as these regulators can withstand a maximum pressure of 1/2 psi (14”WC).. If the Line pressure is beyond this limit, a step-down regulator will be required.. Double- check the arrow forged onto the bottom of the regulator body which shows gas flow directions; it should point downstream to the appliance.. The red air-vent cap is part of the regulator and should not be removed unless local codes require external venting..
Regulators can be adjusted in the field, but it is recommended that they not be tampered with unless that part is known to be out of adjustment or serious pressure fluctuations are found to exist and can be solved no other way.. Any adjustments to regulators must be made by qualified service personnel with the proper test equipment..
If a vent line from the gas appliance pressure regulator is used, it should be installed to the outdoors in accordance with local codes or, in the absence of local codes, with the National Fuel code, ANSI Z223..1, Natural Gas Installation Code, CAN/CGA-B149..1 or the Propane Installation Code, CAN/CGA-B149..2, as applicable..
WARNING: Failure to install a pressure regulator will void the equipment warranty!
