Installation Base The boiler should be mounted on a level, non-com- bustible surface. Boiler must not be installed on carpeting. The boiler can be installed on a combustible surface only when a suitable floor shield base is pro- vided. Raypak offers an optional floor shield base which can be factory installed on all indoor models except Model 133; the Model 133 floor shield base is shipped loose and must be installed by the contractor. Do NOT use the shipping crate base as an installation base.

Vent Piping WARNING: Indoor boilers require a drafthood that must be connected to a vent pipe and properly vented to the outside. Failure to follow this procedure can cause fire or fatal carbon monoxide poisoning. Vent piping the same size or larger than the drafthood outlet is recommended, however, when the total vent height is at least 10 ft. (drafthood relief opening to vent terminal), the vent pipe size may be reduced as spec- ified in Chapter 10 of the latest edition of the National Fu
