c) Repeat step (a), making adjustments to the gas valve, until flame is established. d) Once flame has been established, set your manifold pressure to the desired value from TABLE 1. 4) Check combustion gases using proper combustion analysis equipment to ensure safe levels of CO and CO dur- ing appliance heat up. -
Page 14: Air Gate Adjustment
AIR GATE ADJUSTMENT To regulate the combustion air, adjust the manual air gate (3), by loos- ening the locking screws (4). Once the optimal adjustment is reached, tighten the locking screws (4). EXAMPLE SETTING - (for natural gas) To set the air intake for a desired burner output of 243,600 Btu/hr, use TABLE 1 to determine the correct air gate setting. -
Page 15: Diaphragm Installation And Combustion Head Setting
DIAPHRAGM INSTALLATION AND COMBUSTION HEAD SETTING A proper diaphragm (C) has to be installed in the combustion head gas line, according to TABLE 1. A complete set of gas diaphragms is delivered with the burner packaging as equipment. The burner leaves the factory with the C6 diaphragm already installed. -
Page 16: Pressure Working Chart
PRESSURE WORKING CHART The chart below shows effects of pressure in the combustion zone on the minimum/maximum burner outputs. In this example, with a maximum operating pressure of 0.6 inches water column in the combustion zone, you will be able to obtain a maximum of 370,000 Btu/h burner output. -
Page 17: Combustion Checks
COMBUSTION CHECKS It is advisable not to exceed a measured reading of 10% CO for Natural Gas or 12% CO for Propane Gas. For safety reasons, the value of .02% (200ppm) free air sample must not be exceeded. IONIZATION CURRENT Red wire connect The minimum amount of current necessary for the control box to operate properly is 3 micro Amps DC. -
