Meet the minimum clearances to combustible construction per the Specification Section of this manual. 1. UNPACk THE CRATE Tip the boiler and shimmy it off the skid. 2. POSITION THE BOILER WARNINGS CLEAN BURNERS DAILY if operating the boiler in a dusty environment.
Vent connector shall be double-wall insulated gas vent as supplied with this boiler or Type B (double-wall) gas vent only. Using sheetmetal screws, attach the vent connector between the vent damper and the vertical chimney (Figure 4-b). Do not exceed the maximum vent connector length in Table 4.1.
SIZE GAS PIPING, regulators, valves, and meters so as to provide an adequate gas flow and pressure to the boiler during operation. Failure to do so may cause poor combustion, noise, injury, or death. Remove boiler door, locate gas valve and remove plastic shipping plug.

The LCD Display is an easy to use touch screen type display that allows a technician to monitor and adjust the IQ Boiler Control and connected IQ Option Cards. All boiler settings, status and error codes are displayed in full text. All Outdoor Reset IQ Option Card parameters are adjustable .
IF YOU SMELL GAS, STOP and repair the leak. Lighting the boiler when gas is leaking may cause explosion or fire. Follow the checklist below: Verify that the venting, water piping, gas piping, and electrical systems are properly installed and checked.
Perform Startup Checks and Adjustments described earlier in this manual. Check operation of airflow sensing switches. Check for water leaks on the boiler or water pooling around boiler. Manually operate the relief valve. If the water is grey or black, there is excessive oxygen in the system.
When a problem occurs with the boiler operation, the Burnham IQ Control System easily provides specific, valuable information to help resolve the issue quickly. The display on the IQ Boiler control should be the first place to check. If "Err" IS Not displayed on the IQ Boiler Control: Use the following table to determine the problem and possible causes.

Ignition failure, overheating, fire, carbon monoxide, and spillage of flue gases may result from poor air supply. If the boiler is a Direct Vent boiler and exchanges all combustion air and combustion products directly with the outdoors, there are no special requirements for providing combustion, ventilation, and dilution air.
Install this boiler according to this manual and the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the Natural Gas and Propane Installation Code, CAN/CSA B149.1, or applicable provisions of the local building codes.
