Page 5: Introduction
The Technology The GoGaS KMI Novus high intensity heater from the KMI series is a high-quality product with ratings from 6 kW (21,000 BTU/h) to 36 kW (125,000 BTU/h). The modern injector burner allows almost pollution-free operation, from the smallest to the largest heater unit, with only one combustion chamber. -
Page 6: General Information
INTRODUCTION This appliance must be installed in accordance with current connection and installation regulations and may only be used in adequately ventilated rooms. The installation and operating instructions must be inspected and understood before installation and before start-up. Before installation it must be checked whether local gas distributions, gas types and gas pressures as well as the settings of the appliance are compatible. -
Page 7: Layout Recommendations
LAYOUT RECOMMENDATIONS Layout Considerations • Because high intensity heaters are un-vented, verify local codes for guidance on air supply and dilution air. Also see section on Ventilation. • Check local codes for mounting requirements and the requirement for flexible gas connectors or rigid mounting. -

Page 15: Electrical Connections
INSTALLATION INSTRUCTIONS Electrical Connections WARNING ◊ For your safety, shut off the main gas valve, and disconnect all electrical supply to the High Intensity Unit. ◊ Ensure the heaters are properly grounded. ◊ Perform all work in accordance with local codes or the National Electric Code ANSI/NFPA 70 or Canadian Electrical Code CSA C22.1. - Page 16 INSTALLATION INSTRUCTIONS Electrical Connections (continued) If mechanical exhaust or humidistat is used in the building, it is typical to interconnect these in the heater circuit as shown in figure below. FAN #2 FAN #1 When using a humidistat to control exhaust HUMIDISTAT fans, wire the humidistat to cause the fan to operate on humidity rise, NOT humidity fall.

PRESSURE SWITCH OPTIONAL FIELD SUPPLIED / WIRED... -
Page 18: Ventilation
INSTALLATION INSTRUCTIONS Ventilation Buildings using high intensity radiant heaters require ventilation. High Intensity type heaters are considered un- vented gas fired appliances, requiring ventilation to supply combustion air and dilute/remove the products of combustion. Requirements for combustion air supply and dilution air vary by jurisdiction, building type and specific installation details. -
Page 19: Operation And Maintenance
OPERATION AND MAINTENANCE • Ensure the gas supply line has been purged. • Open all gas cocks to the heaters and electrically energize the system. • Follow the instructions on the heaters Lighting Instructions Label. • Check ensure that thermostat starts and shuts down the system. -
