GAS SPECIFICATIONS
GAS CONNECTIONS
Domestic and General Export installations
The gas line should be large enough to accommoĆ
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 conĆ
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 a y pipe ru s over 50 feet (15 m), co Ć
sult the factory.
CE approved installations
1. Connect the oven to the gas line with the propĆ
er type of gas according to Local and National
Installation Standards. See TABLE 2.
GAS RE UIREMENTS
The firing rate for the MT2136G is 55,000 BTU/Hr.
(16 kW/Hr.)
NOTE: For atural gas meter sizi g, co sult your
local gas compa y to e sure that your meĆ
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.
