king KBP Compact Unit Heaters

INTRODUCTION

KBP unit heaters are to be operated at voltage listed on the rating label. It is important that you verify the power supply voltage is the same as the nameplate voltage of the heater. Connecting the heater to an improper voltage or failure to follow the procedures as outlined in this manual can result in damage to the heater and void the warranty. This heater is provided with a factory installed thermostat. Disconnect all power from the heater at the main service panel before attempting to install or service this unit. All electrical wiring must conform to local electrical codes. Heater circuit must be properly protected.

INSTALLATION INSTRUCTIONS

TOOLS NEEDED:

• Screwdriver (Phillips & Slotted)
• Wire Cutters
• Pliers
• Adjustable Wrench
• Electric Drill

HARDWARE NEEDED:

• Adequate gauge & length of wire for your application
• Proper size fuses or breakers to handle amperage
• Proper wire connectors for your application
• Fasteners appropriate size to mount heater

MOUNTING HEIGHT:
When the air flow of the heater is directed vertically or horizontally, the minimum mounting height is 6 feet in the USA and 8 feet in Canada. Mounting heights depend upon building utilization and heater KW capacity.

LOCATION OF HEATER:
The heater should be installed 6 feet above floor and according to minimum clearance chart (Figure 1) The direction of airflow should not be restricted by machinery, beams, etc., and the air flow should run with walls, rather than blowing directly at them. When more than one heater is used in an area, the heaters should be arranged so that the air discharge of each heater supports the air flow of the others to provide best circulation of warm air. (see figure 4).

MOUNTING HEATER:
Wall stud and ceiling joists are typically wider than our mounting bracket which is 11 inches wide. The heater weighs 14 lbs. and should be mounted onto at least one stud to be properly supported. Your fasteners penetrating a stud is critical to supporting the weight. A gypsum wall board fastener is not strong enough. But if your ideal location has no solid backing, you can fasten with large screw fasteners a 2″ x 6″ board to ceiling joists or wall studs. Attach with appropriate lag bolts with proper depth for the 14 lbs. Install wing nut fasteners into the outside of the bracket and star washer between the heater and bracket. Be certain adjustment knobs are tightened firmly to secure the heater to swivel bracket.
