PART I. COMBUSTION AIR AND VENTILATION If a MUNCHKIN OFB is being used for a retrofit and is installed in a full basement with ade- quate infiltration for combustion air it may be installed in the usual way following accepted industry guidelines and good industry practices.
NFPA-211 should be used as a reference. BAROMETRIC DAMPER The MUNCHKIN OFB boiler does not normally require a barometric damper, but, it may be required when the draft in the venting system is stronger than required, and the burner is incapable of operating against a high negative over-fire pressure.
Standard roof clearances apply. It is the responsibility of the installer to ensure they are ade- quate. C. HEAT EXTRACTORS The MUNCHKIN OFB oil fired boiler is not approved for use with a heat extractor mounted in the breeching or fluepipe. PART III. NATURAL DRAFT APPLICATIONS...
• Chimney connectors should be free of as many 90° degree turns as possible, and be pitched upwards towards the vent. It is important to note that due to the high efficiency of the MUNCHKIN OFB boilers con- densing temperatures in the chimney connector and venting system may be reached.
POWER VENTER APPLICATIONS • At least 1' from any roof soffit or ridge vent. • At least 7' above any public walkway. • All of the vent construction should consist of suitable materials and terminate at an approved stainless steel hood. •...
DIRECT VENT APPLICATIONS PART VI. DIRECT VENT APPLICATIONS When using MUNCHKIN OFB- Models 3MOFB, 4MOFB AND 5MOFB on 'sealed' or 'direct' vented systems, they must be ordered from the factory with a Direct Vent System manu- factured by Flex-L International, Inc. whose part numbers are at the end of this section.
DIRECT VENT APPLICATIONS adapter should be fully inserted into the inner vent tube until it's tight. The seams of both tubes must be aligned for ease of insertion. If the adapter does not completely screw into the vent pipe, unscrew it and try again repeating Step 4 page 7. 5) Seal around edge of vent pipe inner tube.
DIRECT VENT APPLICATIONS 8) Seal with a weatherproof sealant around the bead and edge of the outer wall plate to pre- vent water from getting inside. C. CONNECTIONS TO OUTSIDE TERMINAL Using Figure 8 and Figure 9 complete the following steps: 1) Slide the inner section over the vent pipe.
MAINTENANCE PART VII. MAINTENANCE HEAT TRANSFER PRODUCTS, INC. and Flex-L International Inc recommends the entire heat- ing system, including the appliance and vent, to be checked annually by a qualified heating professional.
