VENTILATION REQUIREMENTS
The hood should completely cover the unit with an overhang of at least 6" (15 cm) on all sides not adja) cent to a wall. The distance from the floor to the lower edge of the hood should not exceed 7' (2.1 m). The ventilation system should replace 80% of the exhaust volume with fresh make up air. TABLE 1 should be used as a guideline.

Installations within the U.S.
The MT3855 requires a 15 Amp, 60HZ, 1F, 208)240VAC, 4 wire service consisting of L1, L2, neutral and ground. See FIGURE 1. Use 90_C wire and size to National Electric or local codes.
Installations outside the U.S.
The MT3855 requires a 15 Amp, 50Hz, 1F, 230 VAC, 3 wire service consisting of L1, neutral and ground. See FIGURE 1. Use 90_C wire and size wire according to local codes.

GAS SPECIFICATIONS
GAS CONNECTIONS
Domestic and General Export installations
The gas line should be large enough to accommo) date the peak demand of all the gas appliances. TABLE 2 reflects a straight line, 50 foot run with no coupling restrictions and no other appliances drawing service. Gas line installations MUST con) form to National Fuel Gas Code NFPA 54/ANSI Z223.1 Sec. 1.4 (Latest Edition). TABLE 2 should be used as a guideline only.
NOTE: For any pipe runs over 50 feet (15 m), con7 sult the factory.
GAS REQUIREMENTS
The firing rate for the MT3855 is 150,000 BTU/Hr. (43.9 kW/Hr.)
NOTE: For natural gas meter sizing, consult your local gas company to ensure that your me7 ter will provide the proper supply.
Installations within the U.S.
1.Add the total BTU's/hr of all the gas appliances.
2.Convert BTU's to cubic ft/hr using the formula Cu Ft/Hr = 1000 BTU/Hr for natural gas.
3.Size the meter accordingly.
Installations outside the U.S.
1.Add the total M3/min of all the appliances.
2.Size the meter accordingly.
