Seal any unused openings in the common venting system. 2. Visu[...]

12 Mounting On vertical vents, the vent damper may be mounted with the actuator in any position. On horizontal vents, do not mount the actuator either directly above or d irectly below the vent pipe; mount the vent damper actuator to the side of the vent. The vent damper is set up for a continuous pilot sys- tem. If the vent damper is installed on [...]

15 Gas Supply Connections The inlet gas connection of the boiler gas valve is 1/2". Provide an adequate gas piping supply line no smaller than 1/2", according to T able H above. Gas piping must have a sediment trap ahead of the boiler gas controls, and a manual shut-off valve locat- ed outside the jacket. All gas piping should be tested a[...]

16 shipped loose. The full open position is appropriate for most systems, and ensures adequate flow through the boiler . If system flow is inadequate, (indicated by excessive temperature drop through the system) the bypass valve can be throttled slightly . Care must be taken against over-throttling which may lead to inadequate flow through the boil[...]
