Propane Orifice sizes indicated for sea level above are factory installed in boiler unless otherwise specified by the local authority. Orifice table is based on a higher heating value between 1000 Btuh and 1009 Btuh for Natural Gas (see III, page 13, if local higher heating value exceeds these numbers).
"pool" in a basement or other space below the leak. A spark or flame from the boiler or other source may ignite the accumulated propane gas causing an explosion or fire. Provide a level, solid foundation for the boiler. Location...
NOT be vented into a chimney or “B” vent. Models V-90, V-120, V-150 and V-180 may be vented into a natural draft chimney or natural draft “B” vent if the factory equipped 3" diameter flue collar and adapter on the boiler is REMOVED and REPLACED by the 5"...
A. Figures 7 and 8 show the allowed venting arrange- ments. The maximum equivalent vent length is 40 feet plus vent terminal for all models except V-180 which has a 20 feet maximum equivalent vent length. Every 90° turn in the vent piping is equivalent to 5 feet of straight run, (eg.
Model/Vent Size NATURAL DRAFT CHIMNEY AND TYPE “B” VENTING V-90, V-120, V-150 and V-180 boilers may be vented into a chimney (see “Chimney and type “B” venting” paragraph on page 4) or into a type “B” vent, ONLY when converted to the 5"...
All vent connector joints must be LIQUID tight. Figure 6b. Venting with “B” vent or metal-lined chimney for V-90, V-120, V-150 and V-180 only Minimum vent connectors diameter is 5 inches. It may have to be upsized to 6 or 7 inches (see Table 2).

2. E. The minimum and maximum gas supply pressure (at the inlet of gas valve) are shown on the boiler rating plate for the type of gas used. Gas supply pressure should never be less than minimum or more than maximum pressure when the boiler or any other appliance is turned on or off.
I. FILLING AND VENTING WATER SYSTEMS A. Fill the system with water. Vent or purge of air. B. Fire the boiler as soon as possible (see following warn- ing and instructions) and bring water temperature to at least 180 degrees, while circulating water in the sys- tem.
Btuh Input = cu. ft. metered in 3 minutes x 1050 Btu/cu.ft. x 20 4. The higher* heating value of gas varies substantially for different localities. Consult with Slant/Fin’s Technical Ser- vice Dept. for re-orificing procedures if any of the following apply: a.
With the main burners firing, remove hose from pressure switch, the one toward front of boiler, see figure 14. (Model V-180 has a single sensing hose.) Gas valve should shut off the main burners. If the main burners do not shut down, shut off the power to the boiler and check for continuity across the pressure switch contacts.
APPENDIX A Removal Of Existing Boiler From Common Vent System "At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining con- nected to the common venting system placed in operation, while the other appliances remaining connected to the com- mon venting system are not in operation."...

5. Check manufacturer's recommendations. 6. Check air supply and venting system. 7. Adjust gas input to that shown on boiler rating plate. REMEDY 1. Increase firing rate to that shown on rating plate. 2. Set low limit controls to maintain a higher water tempera- ture.
If the boiler is used to supply hot water to heating coils in air handling units, flow control valves or other devices must be installed to prevent gravity circulation of water in the coils dur- ing the cooling cycle.
