NOTICE

Connecting the thermostat with a voltage other than 24V may damage the heater. The HL3 Series 
requires a 24V connection to the thermostat. This is either supplied by the heater internally (standard) or 
by an external transformer (with optional isolation relays, P/N: HLRP). See Figure 3.30

HL3 Series heaters require a 24VAC, two-stage thermostat to operate. The burner control box is equipped 
with a round terminal strip that accepts three (3) 1/4” insulated female spade terminals.  Do not supply 
120V to the 24V connection. 

The HL3 Series is equipped with or without relays (P/N: HLRP). The optional relays must be factory 
installed.  

NOTE:

 Units with a relay installed must have an external transformer (field supplied), see wiring 

diagram. (See Figure 3.31B).

  Standard Configuration 

 

Without relays (identified with white label around the terminal block): 

 

•   Single burner control box. 

 

•   Single thermostat.

  Optional Configuration 

 

With relays (identified with orange label around the terminal block): 

 

•  A single thermostat controls two or more burner control boxes. 

 

•   Heaters are common vented. 

 

•  Must be factory installed.

•  This heater must be electrically grounded in accordance with the Canadian Electrical Code C22.1 

(latest edition).

•  Applications must conform to the Canadian Electrical Codes C22.1 (latest edition) when an external 

electrical source is used.

•  Refer to the rating label on heater for the required amperage rating.
•  Under no circumstance is the electrical supply line to the heater to provide any assistance in the 

suspension of the heater.

•  Neither the electrical supply line nor sprinkler heads shall be located within the minimum clearances 

to combustibles.
