Call a qualified service technician.
SECTION 1 INSTALLATION 1.1) - DANGER, WARNING AND CAUTION The words DANGER, WARNING and CAUTION are used to identify the levels of seriousness of certain hazards. It is important that you understand their meaning. You will notice these words in the manual as follows: 1.4) A 4’’ long nipple ¼’’ NPT and a ¼’’NPT coupling if unit is installed upright position, water connections at the bottom. INSTALLATION DANGER WARNING Immediate hazards which WILL result in death or serious injury.
Figure 1 : Mounting configurations 1.5) CLEARANCES The following clearances should be provided for the servicing of the unit: Table 1 Minimum clearances to combustible materials LOCATION Access side to elements Sides Bottom (water connections) Front* Back CLEARANCE 13 ¼‘’ (34 cm) 4’’ (10 cm) 6 5/8’’ (17 cm) 0 0 * If the boiler is in an enclosure, provide a door or a removable panel in front to access the control panel. 1.
Figure 2 : Boiler components Freeze protection (when required) WARNING Only propylene glycol may be used in this hydronic heating system, to prevent freezing. b. 1 expansion tank, pre-pressurized to 12 psi and of appropriate size; c. 1 or more automatic air purge valves; d. 1 or more circulating pumps of appropriate capacity. CAUTION To avoid water damage and/or scalding due to relief valve operation, a discharge line must be connected to the valve outlet and run to a drainage area.
the 3/8’’ NPT to ¼’’ NPT reducer, which is provided; In all other mounting position, cork the hole with the ¼’’ plug provided. 4. Install the water supply and return piping with the 1” NPT fitting; 5. The heating supply line must include: a. 1 circulator along with 2 maintenance valves; b. 1 automatic pressure reducing valve adjusted to 12 psi, with a shut-off valve on the return water line; c. 1 expansion tank; d. 1 automatic vent.
SECTION 2 OPERATION 2.1) ADJUSTMENTS AND START-UP 1. Adjust the setpoint of the boiler on the electronic control. See control section for adjustments. 2. Turn on the power, set the thermostat at 30C (85F). The circulator; The circulator should start as well as the electrical elements in sequence with a 15 seconds delay; 3. The circulator stays on for as long as there is a call for heat except if differently configured on the electronic control.
From normal mode (blue), press OK for 3 seconds to enter the main programmation mode. The backlight will change for green.
The heating slope calculation delay parameter allows modifying the variation of the boiler temperature against the target temperature. Shorter is this delay, better the boiler temperature will be against the target temperature. By cons, the heating cycles will be shorter and numerous which will impair the relays lifetime. Depending installation conditions, it is recommended to keep this delay higher as possible keeping the comfort in avoiding excessive ambiant temperature variations.
MODE 2 : ALARMS SETUP MODE DEF The mode DEF allows to reset the electronic control to its defaults parameters.

SECTION 3 MAINTENANCE The property owner has the following responsibilities: It is recommended that the boiler be purged annually, in order to eliminate sediment and sludge that may have accumulated at the bottom of the boiler and covered the heating elements. a. To maintain the area around the boiler clean at all times and free from combustible and highly flammable material; b. To ensure that the ambient air at the boiler is not excessively dusty or humid; Procedure: c.
