The pH of the neutralized condensate discharged from the reservoir should be checked at 30 day intervals. A pH meter or indicating test strips may be used to monitor the relative acidity of the con den sate. When the pH of the condensate discharged from the reservoir can not be maintained above a pH of 6.0, the calcium carbonate must be recharged. Recharge packages of reagent grade calcium carbonate are available from your distributor. Replenishing the Neutralizer All of the depleted calcium carbonate must be removed from the reservoir and properly disposed of. Rinse and clean the reservoir thoroughly before adding the new charge to the system. Ensure that the piping to and from the reservoir is clear with no obstructions. Add the new reagent grade calcium carbonate in an even layer over the bottom of the reservoir. Replace the top on the reservoir, replace the two straps to secure the top and return the appliance to service. Check the related piping for leaks on the initial firing after the system is recharged. 1. Locate the condensate trap kit shipped loose with the appliance. The kit includes a sheet metal mounting base, two (2) nuts and the condensate trap. 2. Install the condensate trap mounting base on the rear of the appliance in the lower left-hand corner as depicted in Figure 73. Use the pre-drilled holes on the appliance to secure the mounting base to the appliance. 3. Secure the condensate trap to the base using the two (2) nuts supplied with the kit. The trap should be oriented so that the barb connections are pointing toward the appliance (Figure 73). 4. Use a level to ensure that the condensate trap is level on its base. Failure to keep the condensate trap level can result in the spillage of flue products from the condensate trap. 5. Locate the two hoses exiting the back of the appliance. Attach the larger hose on the appliance to the lower barb connection on the condensate trap. Secure the hose to the barb with a field supplied hose clamp (Figure 73). 6. Attach the upper hose on the unit to the upper barb connection on the condensate trap. Secure the hose to the barb with a field supplied hose clamp (Figure 73). 7. Route the wire connector harness from the condensate trap to the matching connector on the lower back of the appliance as shown in Figure 73. This is the blocked drain safety switch. This switch will shut the appliance off if the condensate trap becomes too full of liquid. 8. Place the appliance in operation. While the appliance is firing, check the 1/2" connection on the condensate trap for flue gas spillage. If spillage is detected, check the routing of the hoses from the appliance to the condensate trap and verify that the trap is level. 9. If spillage is still occurring, shut the appliance off. Remove the four (4) screws securing the top cover to the condensate trap and remove the cover (Figure 73). 10. Locate the plastic ball inside the float tube. The ball prevents flue gas spillage from the condensate trap when there is not enough liquid in the trap to raise it and drain. Verify there is nothing under the ball causing it to not seat properly. 11. Replace the top cover on the condensate trap. Re-install the four (4) screws removed in Step 9 to secure the top cover. 12. A 1/2" pipe connection is supplied on the condensate trap. Connect a suitable pipe or tube to this connection (see Figure 73). 54 55 WARNING Use a level to ensure that the condensate trap is level on its base. Failure to keep the condensate trap level can result in the spillage of flue products from the condensate trap. Failure to follow this warning could result in product damage or improper operation, personal injury, or death. NOTE: Use materials approved by the authority having jurisdiction. In the absence of other authority, PVC and CPVC pipe must comply with ASTM D1785 or D2845. Cement and primer must comply with ASME D2564 or F493. For Canada use CSA or ULC certified PVC or CPVC pipe, fittings, and cement. 13. Slope the condensate line down and away from the appliance into a drain or condensate neutralizing filter. Do not expose the condensate line to freezing temperatures. NOTE: The condensate line must remain unobstructed, allowing free flow of condensate. If condensate is allowed to freeze in the line or if the line is obstructed in any other manner, the blocked drain safety switch will prevent the appliance from firing. FIG. 73 Install Condensate Trap LIGHTING INSTRUCTIONS FOR YOUR SAFETY, READ BEFORE OPERATING WARNING If the information in this manual is not followed exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand. B. BEFORE OPERATING, smell around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle to the floor. • Do not try to li...
