This is not a developer question. PXE is normally controlled through DHCP attributes that point the client to the correct PXE server; it's best to search for the Operating System that you use (Windows?) to find out how to configure your DHCP server.
It's not relevant that clients are in a different subnet than your PXE server, as long as routing is enabled and possible between client and PXE server and as long as the clients will receive the proper DHCP response with information about the PXE server. IP helpers is one way of doing that and is configured on the L3/vlan interface where the clients are, and in that case the ip helper should point to your DHCP server where you create the scope for the client VLAN.
