This application manual is intended to provide the piping and control
method for applying multiple Jaguar J-390C boilers to a space heat-
ing and domestic hot water heating system. Use this manual, in
conjunction with the Jaguar J-390C Installation and Operating
Instructions, publication J-40.
The following sections of the Installation and Operating Instructions
(J-390C) must be adhered to:
1. Boiler location and foundation
2. Clearances to combustibles
3. Contamination prevention
4. Air supply and ventilation
5. Venting application and materials*
6. Water treatment
7. Condensate disposal
8. Operating instructions
9. Care and Maintenance
*Common venting of these appliances is not permitted. Direct vent
terminals cannot be clustered together or stacked vertically. Direct
vent terminals can be mounted side by side horizontally, provided
there is a 12" minimum distance between them.
There are two methods available to control J-390C Caravan boilers:
1. Jaguar link method to operate up to 8 boilers. An optional system
sensor is required for operation of this method. Supply water
system sensor (Part no. 833433000) max be ordered to
Slant/Fin boiler distributor.
2. External signal (0-10 Vdc input). Control such as Tekmar control
265 or 275 (operates up to 4 boilers). Energy Management
System may be used with this method. One optional interface
control is required for operation of each boiler in the system.
Part number for interface control kit is 830130000.
Jaguar boilers may also be used in a heating system with a
Caravan cast iron modular boiler system. Since high efficiency con-
densing boilers only condense when the return water temperature is
low, around 130 F or lower, it makes sense to use a lower cost
Caravan cast iron boiler at higher water temperature. We call a com-
bination Caravan Cast Iron Modular Boiler used in a system with a
Jaguar Multiple Boiler a “Hybrid Boiler System”. We address Hybrid
Boiler Systems within this manual.
