The EZBoiler is a packaged system complete with boiler vessel, expansion tank,
air eliminator and circulating pump. It is designed to be used in a variety of
radiant hydronic heating applications. These include radiant floor, baseboard or
radiator heating. These applications can be single or multiple zones. If any single
zone provides less than the minimum required GPM of the boiler, an Electro
Industries' zone controller option is highly recommended.
This series is equipped for load management interrupt with backup boiler output.
Electro Zone Controller models EB-ZEA-1 and EB-ZES8
Electro Dual Fuel Control Module EB-S-SB
The included expansion tank is shipped loose within the EZBoiler enclosure. The
expansion tank must be installed prior to filling the system. See Mechanical
Installation section.

Page 3: Introduction
INTRODUCTION The EZBoiler has been designed to be the complete system package for radiant heat applications. When properly sized, the EZBoiler will provide the needed hot water to properly heat a space in a single zone or multiple zone application. With its unique WarmFlo technology, the EZBoiler can easily modulate output based on the level of demand from a single or multi-zone system. -

2. Prevents over control or false staging up and down when the temperature sensors are attempting to regulate – since Electro Industries’ zone controllers have staging smarts, the addition of the zone controller will provide smoother boiler temperature control. The zone board has a dial switch for each zone and the installer selects one of four zone capacity sizes. -

C. Quick response, hydronic tubing just under the concrete surface, no flooring material over the concrete – in this case, heated water can directly radiate into the room, a standard wall mount room thermostat is adequate. Mount room thermostat on an inside wall similar to most heating systems. TWO-TEMPERATURE OPERATION OR FEATURE When using Electro’s zone controller in priority mode, the boiler system can automatically raise the outlet temperature with zone 1 calling. -

Page 8: Mechanical Installation - Under-Floor Radiation
MECHANICAL INSTALLATION – UNDER-FLOOR RADIATION CAUTION Electro Industries requires the use of dielectric isolation between the boiler supply and return piping when the boiler is plumbed using copper or any other dissimilar metal. Damage to the vessel caused by galvanic corrosion voids Electro Industries’ warranty. - Page 9 5. Piping between the EZBoiler and hydronic system manifolds is shown on drawing BX603. When following this diagram, the water fill procedure becomes very simple and almost guarantees the removal of all air or prevents air locking problems. Experienced hydronic heating installers may be able to eliminate some components but the inclusion of these components guarantees installation and initial operating success.

ELECTRICAL HOOKUP Reference drawing BH601 1. 240/208-Volt Heating Power – route and install the proper current carrying conductors from service panel fuse or circuit breaker. See Specification Table and/or product nameplate for ratings. These models contain built-in circuit breakers and meet the requirement for local disconnect for appliances greater than 10 kW. -

9. Flow Switch– a flow switch is not included or factory required for the boiler. However, one can be added to the LMC circuit. Simply place the field provided flow switch in series with this circuit. NOTE: The L/W (J3) jumper must be in the W position. WATER ADDITIVES/TREATMENT Water treatment is strongly suggested to prevent scale deposits, corrosion from acids, oxygen, and other harmful elements within the specific water supply. -

Staging/Modulating Jumper The control board on the EZBoiler is a universal controller with the capability of interfacing with many different models of TS Electro-Boilers. The correct setting of this jumper is determined on the model of the boiler you are working with. -

Manual Reset Hi-Limit At the top of the vessel there will be either two or three surface mount hi-limits preset at 205° F. There is no light indicator associated with these safety hi-limits. Also these 205° F safety limits break the L2 current carrying 240/208-volt wire going to the elements. -

Page 16: Troubleshooting/Repair Helps
TROUBLESHOOTING/REPAIR HELPS 1. This WarmFlo controller contains several interference suppression components, but as an electronic logic product, unpredictable and unusual transients or interference may sometimes cause strange results. If the WarmFlo controller is acting strange, one immediate step would be power down reset. Simply turn off boiler power or breaker number 1, when the green LED goes out, count to 1Ø, and re-energize power supply. -
