02. OPERATION
The EasyStove allows the simple and safe integration of a solid fuel stove into a conventional central heating
system, allowing the automatic use of heat from the stove when it is available.
The stove circuit is normally an open circuit operating at atmospheric pressure while a modern central heating
system may be a sealed system operating at a higher pressure. The EasyStove RC provides hydraulic separa-
tion between these circuits via a plate heat exchanger and works equally well in both open and sealed systems.
The EasyStove operates automatically, supplying heat to the heating system when the stove is in operation.
The central heating system is fed with hot water from the gas/oil boiler until the solid fuel boiler has reached a
suitable operating temperature. When this temperature is reached, the stove supplies heat to the central heating
system. If heat is no longer available from the stove, then the stove circuit is switched off.
The recommended method of detecting that the stove is in operation is by using a suitable flue thermostat. A
flue thermostat is supplied with the EasyStove.
WARNING
Carefully read the instructions contained in the manual as they provide important information re-
garding safe installation and maintenance. The installation and maintenance must be performed in
accordance with current standards and according to the manufacturer’s instructions.
In the case of failure or malfunction of the appliance, do not attempt to repair it yourself. Please contact RVR
Energy Technology Ltd by email at [e-mail].

Incorrect design and installation may lead to unsafe operation resulting in injury, death or property
damage.
ELECTRICAL HAZARD!
The unit contains live equipment. Disconnect the power supply before working on this equipment.
BURN HAZARD!
The equipment may become very hot in normal operation. Do not touch the equipment while in use.
SCALD HAZARD!
Hot water heated by solid fuel stoves may become very hot. A suitable control device such as a
blending valve should be fitted to the domestic hot water supply to ensure that users are not ex-
posed to scalding hot water.

05. SYSTEM LAYOUT
FUNDAMENTAL REQUIREMENTS
System designers and installers should use their experience, comply with all standards and best practice, and
must ensure that the following fundamental requirements are met:
1. The solid fuel circuit should be “open vented” and fitted with a suitable expansion tank and vent pipe.
2. A permanent heat load, capable of operating in the event of power failure, should be available to dissipate
heat from the solid fuel system and prevent “pitching” to the expansion tank. The EasyStove Heat Dissipa-
tion kit is a good solution for safe heat dissipation.
3. A suitable and approved blending valve must be fitted to the domestic hot water supply to ensure that the
possibility of excessively hot water being delivered to water outlets is eliminated. Hot water may become very
hot when heated by solid fuel. If this is delivered to water outlets, it may cause scalds and burns.
SUGGESTED SYSTEM LAYOUT
The scheme below will suit many systems. It takes account of the fundamental requirements outlined above.
Some stoves and boilers will have a heat dissipation facility but if this is not present, the EasyStove heat dis-
sipation kit should be installed as shown. The heat dissipation kit should be installed on the feed and expan-
sion pipes as indicated. Dimension L should not be less than 500mm and the heat dissipation kit should be
at least 800mm below the expansion tank.

tate maintenance operations.
WALL MOUNTING
The EasyStove is normally supplied without a cover. If the unit is equipped with a cover, it should be re-
moved and placed in a safe place. The cover is attached to the frame using four screws, two on the top and
two on the bottom.
WITHOUT COVER WITH COVER
Installation requires no. 4 screws Ø 8mm (not included),
suitable for the type of wall. The position must be selected to
allow easy connection of the pipes to the appliance.
Once you have chosen the position of the unit, confirm that
clearances for service are maintained and that the wall and fix-
ings are robust enough to support the weight of the appliance.

EasyStove Installation, Usage and Maintenance Instructions
MOUNTING OF FLUE THERMOSTAT
Ensure that the flue thermostat is firmly and securely inserted in or bonded to the flue pipe.
WATER CONNECTION
The water connections are at the bottom of the unit. Where pipe connections are rigid, flexible connections
may be used to compensate for mechanical and thermal stresses.
IMPORTANT
Isolation valves should be fitted to all connections to facilitate maintenance operations.
All water connections are female threaded with a union in accordance with ISO 228/1 G3 / 4 “F.
CAUTION
Take care when tightening the unit connections to avoid distortion of the copper tubes. Do not apply
excessive torque and support connections adequately.
CAUTION
All units are pressure tested with water. It is possible that seals have suffered a natural volume
reduction due to drying. The installer should check all connections and tighten them if necessary
to restore the compression of the gasket. The installer is responsible for ensuring that the entire
system is watertight.
NOTE
Ensure thorough flushing of the system, to eliminate dirt, before commissioning.

09. COMMISSIONING
Before operating the equipment, ensure that all air is purged from the EasyStove using the appropriate manual
air vents and that the pump impeller of the pump is free to rotate. Ensure that all air is purged from the EasyS-
tove Heat Dissipation kit (if used). The presence of air in the primary stove circuit will prevent normal circulation.
Once the installation is complete and after checking that all of the electrical and hydraulic connections are cor-
rect, the unit can be started by switching on the power supply.
CIRCULATION CONTROL
Set the pump control to match the type of system. In most cases, the Δp-c operating mode is a good choice.
Operating mode: Δp-c
The electronic control maintains a constant differential pressure generated by the pump at the set-point Hs.
Operating mode: Δp-v
The electronic control varies the set-point of the differential pressure to maintaining linear pump operation be-
tween Hs and ½Hs
Air Purging Function:
An integrated purging function alternates high and low speed pump operation for 10 minutes after start up.
