If the heater needs to be secured to the ground, usethe holes in the anchoring legs on the heater.ClearancesIndoor InstallationsWhen installed according to the listed minimum clear-ances from combustible construction, these heaterscan be serviced without removing permanent structur-al construction around the heater. However, for easeof servicing, we recommend a clearance of at least 24in. in front, at least 24 in. on the rear and 24 in. abovethe top of the heater. This will allow the heater to beserviced in its installed location without movement orremoval of the heater.Service clearances less than the minimum mayrequire removal of the heater to service either the heatexchanger or the burner components. In either case,the heater must be installed in a manner that willenable the heater to be serviced without removing anystructure around the heater.Outdoor InstallationsThese heaters are design-certified for outdoor installa-tion. Heaters must not be installed under an overhangunless clearances are in accordance with local instal-lation codes and the requirements of the gas supplier.Three sides must be open in the area under the over-hang. Roof water drainage must be diverted awayfrom heaters installed under overhangs.Equipment BaseThe heater must be mounted on a level, structural-ly sound surface. The heater is approved forinstallation on a combustible surface but must NEVERbe installed on carpeting.
