Anleitung Zusammenfassung
The heater must be placed in a suitable room on a non-combustible floor or on a non-combustible base and in an area where leakage from heat exchanger or water connections will not result in damage to the area adjacent to the heater or the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan with adequate drainage, be installed under the heater. The pan must not restrict air flow. Rev. E 11-5-07 Installations in basements, garages, or underground structures where flammable liquids may be stored must have the heater elevated 18 inches from the floor using a non-combustible base. The following minimum clearances from combustible materials must be provided. Side Front Back Top Water Connection 18 in. 24 in. Remaining 6 in. 6 in.

CAUTION Chemicals should not be stored near the heater installation. Combustion air can be contaminated by corrosive chemical fumes which can void the warranty. NOTE The heater requires two uninterrupted air supply openings; one for ventilation and one to supply oxygen for proper gas combustion. The air supply openings should be sized according to Tables 12. and 13. Air supply requirements below apply to all MiniMax® heaters All opening sizes are minimum and unobstructed. INSTALLATION ON FLOORS CONSTRUCTED OF COMBUSTIBLE MATERIALS The heater may be placed on a “combustible floor” using either of the two methods listed below: a) Use a Non-combustible Base Kit for use on combustible floors. b) Construct a non-combustible base from masonry blocks as illustrated, see Figure 17. Installation (contd.) STACK TYPE INDOOR DRAFT HOOD KIT The proper draft hood and adapter must be installed on the heater as shown below: Screw (2 PLC's) HEATER Top Cover Adaptor Draft Hood INDOOR DRAFT HOOD INSTALLATION 1. Take out the louvered outer top piece after first removing the sheet metal screws, attaching it to the cabinet. 2. Install the adaptor (vent kit). 3. Install the top cover (vent kit). 4. Install the draft hood (vent kit). Use the provided screws to secure the vent assembly. Figure 18. 17 Installation (contd.)
