  • Page 4: Ecs Fire Won't Light After Repeated Attempts

    — ECS FIRE WON'T LIGHT AFTER REPEATED ATTEMPTS Note: The ECS pilot shuts off each time the fire is extinguished and re-lights each time the fire is started. When operating correctly, the pilot spark ceases as soon as the pilot flame is established, and the main burners ignite automatically shortly thereafter.
  • Page 5: Spark Ok, But Pilot Refuses To Light (Not Ecs)

    — SPARK OK BUT PILOT REFUSES TO LIGHT (Not ECS) FIRST :- • Check that all shut-off valves in the gas supply are open. • For LPG models, check for gas in the bottle and open the bottle valve. • Check for a gas smell near the pilot, and wait for it to disperse before starting this procedure.

ERRATIC OPERATION ROOM TEMPERATURE FLUCTUATES TOO WIDELY Ensure that the wall thermostat or hand unit are exposed to free-flowing room air but not in draughts or too close to windows. HEATER CYCLES ON AND OFF TOO FREQUENTLY Move the wall unit or hand unit further away from the heater, ensuring that it is exposed to free-flowing room air but not in draughts or near windows.
  • Page 10: Baltimore & Monaco Assembly And Dis-Assembly

    BALTIMORE & MONACO ASSEMBLY AND DIS-ASSEMBLY REMOVING THE GLASS Remove the louvre assembly by lifting it up about 5mm and pulling it carefully toward you. Remove the dress guard if fitted. For the Baltimore, first remove the front panel (below the glass). Do this by removing the two retaining plates underneath the front panel, and then lifting its rear corners off their support posts.
  • Page 11 channel. Maintaining the backward pressure, slide the front glass down into the channel. For safety, strap the glasses together with a piece of adhesive tape at each top corner to prevent them from falling out while the top trim is being fitted. Slide the top trim into position under its guides and replace the two horizontal retaining screws.
  • Page 12: Disconnecting The Flue

    DISCONNECTING THE FLUE Shut off the gas supply at the valve behind the heater. Remove the access panel on the rear of the cabinet. Disconnect the gas line at the heater. Lift the flue sleeve about 75mm and support it with a wooden block. Slacken any flue clamp and lift the flue while moving the heater from beneath it.

  • Page 15: Accessing The Main Injectors

    1.10 ACCESSING THE MAIN INJECTORS Remove the burners (See 1.7) The injectors can now be unscrewed from the manifold. WARNING. On some models the jet sizes in the front and back injectors are different. Take care not to mix them up. (See Table 3). Note.
  • Page 16: Removing And Replacing The Pedestal And Pedestal Foot

    1.12.2 ACC and RMT Models These have the fan assembly mounted inside the pedestal rear panel. A thermodisc switch is fitted adjacent to the rear of the firebox. Un-plug the lead from the mains supply. Remove the four retaining screws at the rear of the pedestal. Lift the fan assembly carefully away from the pedestal until the loom connector block is exposed.
  • Page 17: Removing And Replacing The Glass

    NAPLES & SEVILLE ASSEMBLY & DIS-ASSEMBLY REMOVING AND REPLACING THE NAPLES GLASS Remove the top louvre assembly and the bottom right louvre assembly by lifting upward, then outward. Swing the bottom left louvre assembly open and lift it off its hinge. If a dress guard is fitted, release it by springing out the clips which hook behind the vertical sides of the glass frame.
  • Page 18: Removing And Replacing Burners

    Confirm correct engagement by pulling forward on the louvre assembly. The bottom left louvre assemblies are hinged for easy access to the controls. To attach (or detach) the bottom left louvre, hold it in a position 60° from fully closed. When attaching, tilt the louvre away from the heater at the top so that the bottom eye of the hinge can be hooked over the bottom hinge pin.

    The injectors can now be unscrewed from the manifold. WARNING. On some models the jet sizes in the front and back injectors are different. Take care not to mix them up. Note. When replacing an injector, it is should not be over-tightened, and a small amount of teflon thread sealant (not tape) should be applied to the thread to prevent gas leakage.
  • Page 20: Accessing And Retro-Fitting The Thermodisc

    Release the fan by removing one screw at each end of the fan mounting plate. On later models the fan mounting screw holes are keyhole slotted, so the fan can be lifted up without slackening the screws. Lift the fan up until the bottom edge of its mounting plate comes clear of the locating slot at the rear of the base of the firebox, disconnect the wiring loom at the plug near the fan, and lift it free.
  • Page 21: Service Adjustments

    SERVICE ADJUSTMENTS GAS PRESSURE ADJUSTMENT All pressure adjustments (except the low pressure on the RMT model) must be made while the heater is operating on the ‘HIGH’ setting. BALTIMORE STD NG. This has a pressure regulator separate from its control valve. The regulator must be set to 1.0 kPa.
  • Page 22: Checking The Flue Draught

    NAPLES and SEVILLE models (NG & LP). The manifold pressure is controlled by a replaceable regulator built into the control valve. The regulator must be changed when converting from one gas to the other. There are two pressure test points on the face of the regulator. The inlet pressure is measured at the lower test point and the outlet pressure at the upper one.

  • Page 25: Remote Control Installation

    REMOTE CONTROL INSTALLATION BALTIMORE & MONACO (ACC models only) NOTE: The receiver should be mounted in the position that gives it best ‘line of sight’ to the hand-held remote control. Options are at either side of the pedestal (at each rear corner) or on the wall alongside the heater.
  • Page 26: Thermostatic Controls

    NAPLES AND SEVILLE Open the left lower louvre assembly to gain access to the control valve. The two terminals on the front face of the valve are normally wired to the on/off switch on the side of the fascia column. In order to retain the function of the on/off switch, the receiver should be wired in series with this circuit.
  • Page 27 When the display shows ‘ON’, the SET TEMP will be displayed below the ROOM TEMP. For the burner to light, the SET TEMP must be higher than the ROOM TEMP. Raise the SET TEMP, if necessary, by pressing the right hand button. Turn the PILOT control fully anticlockwise to the ‘ON’...
  • Page 28: Receiver Switch Positions

    Check that the power switch at the wall is ‘ON’ and press the top round handpiece button while aiming the handpiece toward the receiver on the right front corner of the pedestal foot. The red indicator light on the handpiece should light and the red indicator light alongside the receiver (on the pedestal foot) should light in response and remain alight after the handpiece button is released.

  • Page 31 If the circuit board is functioning correctly and a valid ‘start fire’ signal has been sent from the receiver, a relay on the pc board will connect J9 to J8. If the thermostat is currently calling for heat, or if the jumper wire is across the thermostat connecting terminals, J8 will then be connected to R2 (on the main relay), and since R1 is permanently connected to J1, there will be a 24v ac supply to the coil of the main relay.
