The proper pressure regulation. (Two-stage regula-tion is recommended from the standpoint of bothcost and efficiency.)3. The pressure drop in the lines between regulatorsand between the second stage regulator and theappliance. Pipe size required will depend on thelength of the pipe run and the total load of all appli-ances.Complete information regarding tank sizing for vapor-ization, recommended regulator settings, and pipe siz-ing is available from most regulator manufacturers andL.P./propane gas suppliers.L.P./propane gas is an excellent solvent and specialpipe compound must be used when assembling pipingfor this gas as it will quickly dissolve white lead or moststandard commercial compounds. Shellac base com-pounds such as Rectorseal #5 are satisfactory for thistype of gas.Check all connections for leaks when piping is com-pleted, using a soap solution. NEVER USE A FLAME.VENT AND COMBUSTION AIR HOODSTwo vent hoods and a combustion air hood (withscreens) are shipped attached to the blower housing inthe blower compartment. These hoods must beinstalled to assure proper unit function. All hoods mustbe fastened to the outside of the gas heat access panelwith the screws provided in the bag also attached tothe blower housing.The screen for the combustion air intake hood issecured to the inside of the access panel opening withfour fasteners and the screws used for mounting thehood to the panel. The top flange of this hood slips inunder the top of the access panel opening when install-ing. Refer to Vent and Combustion Air Hood Figure 8.Each vent hood is installed by inserting the top flangeof the hood into the slotted opening in the access paneland securing in place.The products of combustion are discharged horizon-tally through these two screened, hooded vent open-ings on the upper gas heat access panel.OPTIONAL ECONOMIZER/MOTORIZED DAMPER RAINHOODThe instruction for the optional economizer/motorizeddamper rain hood can be found in form 035-19854-000. Use these instructions when field assembling aneconomizer rain hood onto a unit. The outdoor andreturn air dampers, the damper actuator, the damperlinkage, the outdoor and return air divider baffles, andall the control sensors are factory mounted as part ofthe "Factory installed" economizer option.FIRE OR EXPLOSION HAZARDFailure to follow the safety warning exactlycould result in serious injury, death or propertydamage.Never test for gas leaks with an open flame.Use a commerically available soap solutionmade specifically for the detection of leaks tocheck all connections. A fire or explosion mayresult causing property damage, personalinjury or loss of life.FIGURE 8 - VENT AND COMBUSTION AIR HOODAn adhesive backed label is provided over theoutside of the combustion air inlet opening toprevent moisture from entering the unit, whichcould cause damage to electrical components.Allow this closure label to remain in place untilthe combustion air hood is to be installed.VENT AIROUTLETHOODSSLOTTEDOPENINGS INACCESS PANELCOMBUSTIONAIR INTAKEHOOD GAS HEATACCESSPANELS
